What is zirconia, exactly?

Zirconium dioxide is the main zirconium oxide. Its chemical formula is ZrO2, and it is white with odorless and tasteless crystals. It is insoluble and insoluble in water and hydrochloric acid. It is chemically inactive. It has high melting points, high resistivity and low thermal expansion. It is an important ceramic insulating material, ceramic sunscreen and ceramic sunscreen.

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. It is used mostly for piezoelectric ceramics, household ceramics and refractory material, as well as precious metal smelting Zirconium zirconium bricks, tubes, crucibles, and other purposes. 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 in epoxy resins to increase corrosion resistance for heat-resistant salt water.


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 high temperatures above 1500°C for extended periods of time. The maximum service temperature is 2200°C. ZrO2’s resistance to acid and alkali corrosion is superior to that of SiO2O3 and Al2O3. Insoluble in water; soluble in sulfuric and hydrofluoric acids; slightly soluble hydrochloric and nitric acids. It can be fused in alkali to create zirconate.
