What is the Application Field of Zirconia

What’s zirconia?

Zirconium dioxide has the chemical formula ZrO2. It is the principal oxide of zirconium. The crystals are usually white with no odor and taste. They can be dissolved in water, hydrochloric, or dilute sulfuric. It is chemically inactive and has properties such as high melting point and high resistance.

Zirconia’s main application areas

The raw materials for metal zirconium or its compounds

It is useful for the production of metal zirconium or zirconium compound, making refractory blocks and crucibles as well as high-frequency ceramics. Most commonly used to make piezoelectric ceramic items, household ceramics and refractory material, precious metal smelting Zirconium blocks, zirconium tubes and crucibles. This is used for the manufacture of non-ferrous metals like steel, iron and glass as well as zirconium dioxide fibres. Ceramic pigments, electrostatic coatings, and baking varnishes all use it. You can use it in epoxy resin to prevent saltwater from corroding.

Refractory

Zirconia fibre is a refractory polycrystalline fiber material. ZrO2 fiber is a high-temperature refractory fibre material that has excellent melting points, resistance to oxidation, and other outstanding properties at high temperatures.

Zirconia fibre can be used at high temperatures above 1500°C for long periods. At 2200°C the maximum service temperature can reach. ZrO2’s resistance to acid and alkali corosions is superior to that of Al2O2 and SiO2. Water insoluble, hydrofluoric and sulfuric acid soluble; slightly solubilized in hydrochloric and nitric acids. Zirconate can be formed by fusing it with alkali.
