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.
