Spherical Quartz Powder Properties And Applications

Spherical quartz powder It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. Then, it is shaped into a round shape with flame melting to get a silica powder that has a low stress, good fluidity, small specific surface, and a small amount of surface area.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including a smooth surface and a large surface area. It is also hard, stable, and has a high degree of chemical resistance.
First, the spherical granules are well-mixed with the resin and form a thin film. The resin content is low, while the quartz powder amount is high. This can result in a mass fraction of up to 90.5%. The more quartz powder that is added to the mold, the less thermal conductivity it has and the smaller its thermal expansion coefficient. The performance of electronic components is improved when they are closer to monocrystalline silicon’s thermal expansion coefficient.

Second, spherical quartz has the lowest stress and highest strength.

Finaly, the spherical shaped powder has a smooth, non-abrasive surface with a low coefficient of friction. It also wears the mold less, which increases its service life by a factor of two.

Spherical quartz powder applications

It has many applications. However, its main market is electronic packaging. Electronic packaging is an important industry that supports integrated circuits. The packaging requirements are increasing as integrated circuits get larger and more sophisticated.

Microelectronic packaging requires a high level of moisture resistance, low radiation, low stress and resistance to dip or reflow soldering. Also, the plastic seal must be good after the integrated circuit has been packaged. Spherical Quartz Powder is an essential support material for EMC. Not only does it need to have a particle size that meets the packaging range, but its purity and radioactive element content must also be low.

Quartz powder, which is spherical in shape, can be used for a variety of purposes, including electronic packaging. It can also be used as a filler in paints or coatings.

The Preparation Methods of Spherical Quartz Powder

Spherical quartz powder Has excellent properties including smooth surface, large surface area specific, high hardness, stable chemical properties. The spherical particles are fluid and can be mixed evenly with resin to create a film. The resin amount is low, while the quartz powder filling is high.
The lower the thermal conductivity and the smaller thermal expansion coefficient the molding compound, the higher the amount of quartz powder. The performance of electronic components is improved when they are closer to monocrystalline silicon’s thermal expansion coefficient.

It is made by purifying and ultra-finely grinding natural quartz stone, and then passing it through a high temperature field. This causes its phase, shape and crystal to change instantly, from a solid to a molten to a solid state. The three most common preparation methods are high-temperature Plasma melting, high-temperature Melting Injection Method and Gas Combustion Flame Method.

High Temperature plasma Melting
The high temperature plasma melting method sprays quartz powder into the plasma flame using high-temperature gases generated by AC/DC arc plasma. The powder is heated to melt and instantly vaporize, then quenched and collected with a cyclone. This produces spherical silica powder. It is characterized as a high heating temperature which can achieve a temperature field more than five times higher than chemical burning (above 3000K). A high temperature, a high heat level and a high active atmosphere cause the chemical reaction to proceed quickly. The result is the rapid formation high temperature phase compounds, which are difficult for liquid phase chemistry to synthesize. Such as nitrides carbides and borides etc. After rapid cooling, particles that have left the plasma will not grow.

The technology of plasma is extremely difficult. First, magnetic and electric properties of plasma can affect the plasma temperature field. The temperature field has a small and concentrated size. Second, the generation of plasma energy by the current through the medium of ionized gases is achieved. A plasma that is too diluted will interfere with the current, and the effect will be lost. It is hard to control how fast the product spheroidizes.

High Temperature Melt Injection
The high-temperature injection method involves melting the material to a liquid by putting it in a hot field. When the melt comes out of the ejector it is sprayed high-pressured air, which breaks up the melt and disperses it into mist. When the droplets cool down, they shrink back into smooth spheres. High temperature melt atomization is the most effective way to guarantee spheroidization. The key technologies of viscous quartz melting atomization in furnaces, high temperature materials for the quartz, and the prevention of secondary pollutants have yet to be developed. This makes it difficult to make high-purity spherical powder.

Gas Combustion Flame method
Gas combustion flames are produced by using acetylene and hydrogen in conjunction with natural gas or other fuels as raw materials. Air or oxygen is used to support the flame. Air is used to transport the angular quartz into the flame. As the angular particles pass through the high temperature flame field, they are first melted to amorphous particle form. It shrinks immediately into spherical powder when it exits the high temperature field. The cyclone then collects the final product. Thermodynamics, gas dynamics and particle hydrodynamics are all involved in this method. The temperature field in plasma high-temperature fires is much lower and there are also fewer factors that influence it. It does not involve electromagnetic theory or the flow ions in an electromagnetic field. It’s easier to control conditions by solving the problem of movement. Equipment manufacturing is simplified, industrialization is easy, and development prospects are better.

Reasons for Spheroidization of Spherical Quartz Powder

What is spherical Quartz Powder?

Spherical Quartz Powder, also known by spherical Silica Powder, is an amorphous powder of quartz that has particles that are spherical in form and whose main constituent is silicon dioxide.

Spherical quartz is used primarily for copper clad laminations and epoxy mold compound fillers within large-scale integrated circuit packaging. However, it also has applications across high-tech areas such as aerospace, fine chemicals, and everyday cosmetics.

Why is Quartz Powder Spheroidized

1. The ball has a small surface area, isotropy, fluidity, and filling quantity. It can have a mass ratio of 90.5%. The filling speed of silica micropowder can be increased.


The filling rate for silicon micropowder is higher, but the thermal expansion factor of the plastic sealing material is lower. In other words, the lower the thermal conductivity, and the closer the thermal expansion of monocrystalline silicon, the better performance of electronic components.


2. The strength and stress concentration of the plastic sealing compound made from spherical dust is the lowest. The plastic sealing compound made of angular powder has a stress concentration equal to 1, but the stress from the spherical is only 0.6. When the spherical dust plastic sealing compound is used to encapsulate the integrated circuit chips, the yield is High. This makes it difficult to cause mechanical damage during transport and installation.


3. Spherical powder’s friction coefficient is low, so the mold wear is very minimal. The mold also has a long service-life. The service life of the mold is doubled when compared to angular powder. The cost of plastic sealing compound packaging molds is high. It is therefore necessary for some to be imported.


4. Silicon micropowder has the ability to strengthen epoxy resin. Spherical powder can also enhance this effect.

The Main Preparation Method of Spherical Quartz Powder

What is spherical Quartz Powder?

After being purified from quartz stone, sphere quartz powder is pulverized and ultrafinely pulverized. The powder then goes through a certain temperature field so that its phase form, crystal form, shape, and state change instantaneously, from solid state into molten state, then to solid state again, then to solid state. Finally, it becomes crystalline. Amorphous powder is made from irregularly angular particles and transformed into regular spherical pieces.

The main preparation method for spherical powder quartz is

1. Flame melting is used primarily to mass produce spheroidized quartz dust. The heating device must have a stable temperature, adjustable temperature ranges, and there is no secondary pollution to quartz powder. This technology is key. The ball-forming principle is that the high-temperature fire spray gun produces a high temperature flame between 1600 and 2000. When the powder enters a high-temperature flame area, its angular surfaces absorb heat. The heat is then transferred to the powder’s interior, where it is completely molten. The action of surface tension means that objects tend to be in a stable condition. Spherical is the best state for forming a ball.


2. The local thermodynamic equilibrium (or thermal plasma) is another name for this plasma. The main feature of thermal plasma is the fact that the plasma’s electron temperature, ion temperature and gas temperature are all almost identical. The thermal plasmas are arc plasma, high frequency and induction plasma.


High-frequency plasmafusion is used for the preparation of spherical quartz. This method has a moderate range, stable control, high output and can achieve a high rate of spheroidization, making it more suitable for production. The principle and procedure are similar to that of flame melting. This mainly transforms the high temperature heat source into an plasma generator.


Compressed air is used as the working gas. The volume of the working gases is 10m3/h. The high-frequency generator generates heat by generating high-temperature gas at 4000-7000. The silica is carried from the top of the plasma reactor furnace to the arc region by the feeder. After melting and gasifying, the powder is then transported through the feeder. After being quenched by a special quencher, the silica powder can then be collected by gravity, cycle (micron scale) or bag dust (nanoscale). In a matter of 1s-2s you can get spherical and nanoscale SiO2 particles.


3. Chemical synthesis

To obtain silica sol, heat the silica emulsion with ammonia or ammonium bicarbonate. The gel is then treated with acid to produce hydrated spherical silica. This product has a low uranium level, which is a characteristic. However, it is also easy to agglomerate.
