What is zirconia, exactly?

Zirconium dioxide, which has the chemical formula ZrO2, the main oxide of zirconium is white, tasteless and odorless crystals. It is insoluble with water, hydrochloric Acid, and dilute-sulfuric acid. It is chemically inactive. It has high melting points, high resistivity and low thermal extension coefficients. These properties make it an important high temperature material, ceramic insulating materials 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, as well as making refractory and crucible bricks and crucibles. Used mainly for piezoelectric ceramics, household ceramics and refractory material, precious metal smelting Zirconium blocks, zirconium tubes and crucibles. This is used for the production of steel and other non-ferrous materials, optical glass, and zirconium dioxide fibres. It’s also used in ceramic pigments, electrostatic coats and baking varnishes. 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. Insoluble in water; soluble in sulfuric and hydrofluoric acids; slightly soluble hydrochloric and nitric acids. It can be fused in alkali to create zirconate.
