The Most Common Method of Producing Zirconia (ZrO2) Powder

What is zirconia

Zirconium Dioxide has the chemical formula ZrO2 and is the zirconium’s main oxide. Normal conditions result in a white, tasteless and odorless crystal. It’s insoluble with water, hydrochloric or dilute sulfuric acid. Chemically, it is inactive. Its properties include high melting point and resistivity, as well as high refractive indices and low thermal expansion coefficients.

Plasma method

A gas is ionized significantly when heated to 3000degC and nearly completely by 5500degC. The electron flow can cause a gas to reach high temperatures when heated by resistance under an electric field. Plasma is the name given to this highly dissociated and thermally conductive gas. Plasma cannot be produced by heating the gas. Rather, it is generated through arc discharge. A plasma spray gun is the easiest plasma generator. In order to generate plasma, two special electrodes are connected with a direct-current voltage. At the same time, an inert gas is passed (nitrogen or argon) between the electrodes. By using a high frequency current or short circuit, a stable DC-arc is created between the two electrodes. This causes the gas to absorb energy, forming a high-temperature flame. The zircon fine-powder sent into flames is instantly decomposed to ZrO2 an SiO2, then SiO2 is evaporated and separated from ZrO2 in order to prepare and purify ZrO2.


The plasma-produced high-purity ZrO2 is a unique material. Plasma ZrO2 has spherical particle size, and the mZrO2 Crystals are extremely fine. The practice has shown that ZrO2 crystalline materials formed at high temperatures are very active, and this is crucial for the production of high performance ceramic materials. Also, the plasma process is continuously being improved.


High-purity ZrO2 has a maximum ZrO2 of 99.6%. Its particle size is adjustable and can be adjusted based on the customer’s needs. The high-purity ZrO2 produced is white. If the ZrO2 level is low, then it will be pale yellow or yellowish brown. Stable zirconia tends to be pale yellow. All zirconia materials mentioned above are in monoclinic phases.

What is the Application Field of Zirconia

What is zirconia, exactly?

Zirconium dioxide, which has the chemical formula ZrO2, the main oxide of zirconium is white, tasteless, odorless crystals that are insoluble in water and hydrochloric acid. It is chemically inactive. It has the properties high melting point and high resistance.

Zirconia’s main application areas

Raw materials and compounds of metal zirconium

It is used for the production of metal zirconium or zirconium compound, making refractory blocks and crucibles as well as high-frequency ceramics. Mainly used to make piezoelectric ceramics, household ceramics and refractory materials, precious metal smelting Zirconium blocks, zirconium tubes, and crucibles. This is used for the production of steel, non-ferrous and optical metals, zirconium dioxide fibres, and optical glass. Also used in ceramic pigments. It can be used to increase corrosion resistance in epoxy resin.


Refractory

Zirconia fiber can be described as a polycrystalline refractory fibre material. ZrO2 has a higher service temp than other refractory fibres like mullite fiber and aluminum silicate fiber due to its high melting point, nonoxidation, and other excellent properties at high temperatures.


Zirconia can be used in an ultra-high-temperature oxidizing environment above 1500°C for up to two years. Its maximum service temperature is at 2200°C. ZrO2’s resistance to acid and alkali corrosion is superior to that of SiO2O3 and Al2O3. It is insoluble when mixed with water. However, it is slightly soluble in hydrofluoric and sulfuric acids. It can be fused in alkali to create zirconate.

What is zirconia toughened alumina?

What is Zirconia Toughened Alumina? The zirconia toughened allumina (ZTA). is composed of zirconia alumina. Zirconia, an oxide of zircon, is commonly added to materials due to its strength. Zirconia toughened Alumina generally has a zirconia proportion between 1/10 to 1/5. You can adjust the ratio to fit the specific product. ZTA ceramics provide the ideal balance between value and price. ZTA ceramics offer superior value than regular alumina. ZTA products also cost less than pure zirconia.

Different between ZTA and ATZ
Zirconia hardened alumina (ZTA), and alumina toughened zinc (ATZ), have similar raw materials. It is important to not confuse these two composites. Alumina toughened zirconia, (ATZ) has a low ratio of alumina and zirconia. Zirconia hardened alumina is (ZTA), and the reverse holds true.

ZTA properties
One of the best characteristics of zirconia-toughened alumina is their high mechanical strength. This is due to a process known as stress-induced Phase Transformation toughening. At room temperature the zirconia toughened Alumina’s density is around 4.3g/cm3.
High heat resistance makes this material suitable for use in high-speed grinding machines. Zirconia hardened alumina’s maximum working temperature is 1923K. The thermal expansion coefficient of the zirconia toughened aluminum is 8.1×10 (– 6) C (– 1). Additionally, the Poisson’s ratio, bending force, and elasticity of zirconia hardened alumina is 0.26130 ksi.

What advantages does Zirconia-toughened Alumina offer?
Its versatility is what makes zirconia hardening alumina so valuable. The first is that zirconia hardened alumina can resist temperatures as high as 1773 K. This makes them an ideal choice to manufacture equipment capable of enduring these extreme temperatures. Alumina zirconia hardened has a higher resistance to corrosion than normal alumina. This makes it extremely durable.

Additionally, the surface of zirconia-toughened alumina is smoother than that of ordinary alumina. You can use it for parts of equipment that are susceptible to wear due to friction. A cost-effective alternative to pure zirconia is zirconia toughened aluminum. It is less expensive than normal zirconia and is still more efficient than ordinary alumina. These materials can also be used in biocompatible applications. They have no side effects on human bodies.

ZTA uses
Valve Seal
Valve seals must be durable when choosing materials. Material durability is important. This standard is met by Zirconia-toughened Alumina and it’s commonly used to seal valves.


Biocompatibility is another characteristic of zirconia-toughened alumina. The composites can also be toughened and have high bending strengths. The zirconia toughened aluminum is an ideal material for joint replacement. Because it is biocompatible, it will not cause injury to the body. Its toughness means that it will be able to support body weight. It’s used in hip replacement.

Cutting instrument
Zirconia hardened alumina from zirconium is wear-resistant and heat-stable. It also has friction resistance. It is an excellent material to use for cutting tools. These materials are less costly than those used in cutting tools like diamonds.

Grinder wheel
A grinder’s most important component is the grinding wheel. Most grinding wheels are made from composite materials. Composite materials are used for making grinding wheels. It’s strong enough to be used in this way. It’s also strong and can be self-sharpening.

Immediate tooth
Due to its biocompatibility zirconia toughened is alumina, it’s commonly used in dental implant manufacturing. Alumina that is zirconia-toughened by zirconia can also be corroded easily. Zirconia dental implants can be made without any harm by being moistened with alumina.

Bushing
Bushings are used to fill in the spaces between these two components. A type of bearing. A finish is often applied to zirconia toughened aluminum. This makes it an excellent bushing. A further reason why it’s used for bushings is its high friction resistance.
