Spherical Alumina Powder And The Applications of Spherical Alumina

One of the thermally conductive material is aluminum. Spherical aluminum oxide It is now a “star product”. High-energy consumption areas like new energy vehicles, 5G, and thermal management encourage the use of spherical. This is why the market for spherical alu continues to grow. Spherical Alumina is widely used not only as a thermal conductive substance but also in advanced ceramics, catalysis and grinding, polishing and composite materials.

Spherical Property

Because of their many crystal shapes and unique chemical and physical properties, Alumina and its Hydrate are used widely in the areas of electronics, petrochemical, refractories ceramics papermaking pharmaceuticals aerospace, and other fields. Alumina’s application capabilities in many areas are directly related to their morphology. The Al2O3 powder particles that are spherical have the best properties. Their morphology is regular, has a lower specific surface area and greater packing density, as well as better fluidity. This can significantly improve product performance.

Spherical Application

Used as Spherical Allumina Powder Thermal Conductive Materials The most significant use of spherical aluminum is thermal conductive material. Spherical alumina can be classified as thermal interface material, thermal-conductive engineering plastics and thermally conductive plastic sealing substances. The thermal interface materials can be used to IC packaging or electronic heat loss. These materials fill in any gaps caused by contact between the materials. This reduces the heat transfer resistance and improves heat dissipation. Inorganic thermal fillers such as sphered aluminum are common. Its thermal conductivity can reach 3042W/m K.

Ceramics using Spherical Allumina Powder
The properties of ceramics can be greatly affected by adding a small amount of spherical aluminum powder to their production. Low temperature brittleness in ceramics has a significant impact on their ability to be used for various purposes. For low-temperature plastic ceramics, you can use ceramic materials with spherical aluminum powder. Additionally, ceramics can be made tougher by using spherical-alumina. It can increase the ceramics’ strength and decrease the melting temperature by reducing the amount of spherical allumina powder to 5.0%.

As a polishing agent, use Spherical Allumina Powder
Spherical or flake-alumina alumina offers better fluidity and dispersion than conventional granular or flake. Because spherical powder abrasives are evenly distributed within polished products, there is no possibility for powder to accumulate in large quantities. The particle surface can also be smooth, which helps avoid scratches and improves polishing.

Spherical Led luminaire Use Both its catalyst and its transporter
High chemical activity is possible because of the large amount of unsaturated chemical bonding and catalytic activ centers that are found on the surface. Spherical Alumina offers the benefits of high chemical activity, low wear, and long service lives. It also boasts a large specific area. It is impossible to replace the performance and characteristics of the catalyst made of spherical aluminum with other materials.

Spherical Alumina Use in 3D printing
Due to its strong strength, high spheroidization rate and resistance to high temperatures, 3D printing is a popular use of sphered-alumina. The advantages of spherical allumina powder include high solid content and good fluidity. They also have high mechanical and chemical properties.

Boron Nitride Properties

Boron nutride is composed of both nitrogen and boron. You can divide the crystal structure into hexagonal oxygen nitride, WBN, and cubic oxygen nitride.
The hexagonal boron-nitride crystal has the same graphite layered structures as graphite. This gives it its name “white graphite”. Theoretical density: 2.27g/cm3, specific gravity: 2.43, Mohr Hardness = 2.
Hexagonalboron nitride is good at electrical insulation, thermal conductivity and chemical stability. Although hexagonal boron-nitride has the same expansion coefficient as quartz, its thermal conductivity exceeds that of quartz by tenfold.
Hexagonalboron nitride is not able to dissolve cold water. The water boils slowly, producing a very small amount of ammonia and boric acids. It is not soluble in hot acids and cannot be broken down with potassium hydroxide and molten sodium hydroxide.

Boron Nitride Properties
1. The heat resistance is high: Sublimation at 3000 at 1800. This strength can also be air-cooled at 1500 to ambient temperature for several dozens of time and not softens at 2800 in inert gases.
2. High thermal conductivity. The hot-pressed products behave the same way as pure iron. And 33W/M.K’s thermal conductivity is higher than that of ceramic materials at 530C.
3, Low thermal expansion coefficient. The thermal shock resistance of ceramics is excellent due to its low expansion coefficient (2 x 10-6).
4. It has excellent electrical characteristics: it is good at insulation at high temperatures (1014 O-cm.2000 at 25 and 1033 O-cm. It’s the most efficient ceramic high-temperature insulating material, with a breakdown voltage 3.0V/MV, low loss of 108HZ 2.5×10-4, and dielectric constant 4. This product is transparent to microwave and ultraviolet.
5. Excellent corrosion resistance: It does not react to iron, copper or aluminum. It is compatible with rare earth metals and precious metals as well as semiconductor materials (germanium-siliconium, potassium arsenide), glass and molten salts (crystals, fluoride, or slag), inorganic acids, and alkali.
6. Low friction coefficient U of 0.16. This is an increase in resistance to high temperatures than graphite or molybdenum sulfide. The oxidation atmosphere can withstand up to 900C and vacuum at 2000.
7. The purity of high purity B is very high. Its impure content is below 10 PPM, while its content in B is greater than 43.6%.
8. Machinability: Its hardness is Morse 2. This allows it to be machined into precise parts using general machining.

How does Aluminum Nitride play a role in the world? The main applications aluminum nitride Powder: Thermal conductive filler, for thermal conductive paste or thermal conductive grease. The aluminum nitride has many uses in photoelectric technology, such as in the optical storage interface, which can serve as an electron substrate, electric induction layer, and wafer carrier. Because of its piezoelectric effects, epitaxial extensions of aluminum nitride crystallines are also useful in detecting surface acoustic signals. On a silicon wafer, the detector is placed. This thin film can be produced only in a few locations. High room temperatures, high temperature strength and low thermal conductivity make aluminum nitride clays ideal for high-temperature structures of heat exchangers. Use aluminum ceramics or their dissolution properties as casting materials for Al, Cu, Ag and Pb can be made.

What properties is aluminum nitride?
AlN It can stabilize up to 2,200. It is sensitive to room temperatures and has a high intensity. However, the intensity drops slowly as temperature increases. Good heat resistance materials have a high thermal conductivity and a low thermal expansion coefficient. The crucible material is ideal for making pure iron, aluminium, and aluminum alloys. It has a low rate of molten metallic erosion. Aluminium nitride can also be used to make an electrical component. Aluminum nitride protects gallium arsenide from ionization during annealing by coating it with aluminum nitride. The aluminum nitride also acts as a catalyst for the conversion of hexagonal to cubic boron nutride. Slow reaction at room temperature with water. You can make this from aluminum powder at 800 to 1000 in an ammonia- or nitrogen atmosphere. The product will be white to gray-blue and it is easily synthesized. You can make it from aluminum powder at 800 to 1000 in ammonia or nitrogen atmosphere. It is then distilled into a gray-white powder using the Al2O3–C-N2 process, which takes place between 1600 and 1750. Aluminum chloride, ammonia can be produced by gas phase reaction.
