Brief Introduction:

Zirconia (chemical formula: ZrO2) is the primary oxide of zirconium, typically appearing as a white, odorless, tasteless crystalline substance and is sparingly soluble in water, hydrochloric acid, and dilute sulfuric acid. It generally contains trace amounts ofHafnium dioxideIt is chemically inert but possesses high melting point, high resistivity, high refractive index, and low coefficient of thermal expansion, making it a crucial high-temperature-resistant material, ceramic insulator, and ceramic opacifier. It is also a primary raw material for artificial diamonds. The energy gap is approximately 5-7 eV.

Usage: Used in the production of zirconium compounds, refractory bricks and crucibles, high-frequency ceramics, abrasive materials, ceramic pigments, and zirconates, mainly for piezoelectric ceramics, daily-use ceramics, refractory materials, and zircon bricks, zircon tubes, crucibles, etc., used in precious metal smelting. Also used in the production of steel and non-ferrous metals, optical glass, and zirconia fibers. Additionally, used in ceramic pigments, static coatings, and baked coatings. In epoxy resins, it enhances resistance to corrosive hot saltwater.
