Zirconia, whose chemical formula is ZrO2, is the main oxide of zirconium. Generally, it is a white odorless and tasteless crystal, which is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. Because of its inert chemical properties, high melting point, high resistivity, high refractive index and low coefficient of thermal expansion, it has become an important high temperature resistant material, ceramic insulating material and ceramic shading agent, and also the main raw material of artificial drill.

Zirconia has excellent properties such as high hardness, high strength, high toughness, high wear resistance and chemical corrosion resistance Zirconia materials have high hardness, high strength, high toughness, high wear resistance and chemical corrosion resistance and other excellent physical and chemical properties. Zirconia has been widely used in ceramics, refractories, machinery, electronics, optics, aerospace, biology, chemistry and other fields.

White or black particles (0.5-2mm, 1-3mm), tablet (diameter: 10x3, diameter: 18x8mm, diameter: 24x14, diameter: 30x10m)

It is suitable for electron gun evaporation. The film is compact, firm and resistant to chemical corrosion. For multilayer.

application area

Raw materials of zirconium and its compounds

It is mainly used for producing zirconium and zirconium compounds, fire-resistant bricks and crucibles, high-frequency ceramics, grinding materials, ceramic pigments and zirconate salts. It is mainly used for piezoelectric ceramic products, daily ceramics, refractory materials and zirconium bricks, zirconium tubes and crucibles for smelting precious metals.

Refractory

Zirconia fiber is a kind of polycrystalline refractory fiber material. Due to the high melting point, non oxidation and other excellent high temperature characteristics of ZrO2, the service temperature of ZrO2 fiber is higher than that of alumina fiber, mullite fiber and aluminum silicate fiber. Zirconia fiber has been used for a long time in the ultra-high temperature oxidation atmosphere above 1500 ℃. The maximum service temperature is as high as 2200 ℃. Even up to 2500 ℃, the zirconia fiber can still maintain its complete shape. Moreover, it has stable high-temperature chemical properties, corrosion resistance, oxidation resistance, thermal shock resistance, non-volatile and pollution-free. It is the most advanced refractory fiber material in the world. The corrosion resistance of ZrO2 is much stronger than that of SiO2 and Al2O3. Insoluble in water, soluble in sulfuric acid and hydrofluoric acid; slightly soluble in hydrochloric acid and nitric acid. It can be fused with alkali to form zirconate. [4]

gas turbine

Great progress has been made in the application of plasma sprayed zirconia thermal barrier coating in aviation and industrial gas turbines, and it has been used in the turbine part of gas turbines to a certain extent.

ceramic material

Zirconia is used as raw material for kiln industry because of its high refractive index, high melting point and strong corrosion resistance.

other

In addition, zirconia can be used in the manufacture of white hot gas lampshade, enamel, white glass and refractory crucible. X-ray photography. Abrasive materials. Together with yttrium, it is used to make light source lamp, thick film circuit, capacitor material, piezoelectric crystal transducer formula in infrared spectrometer.
