Zirconia Ceramic:
Zirconium dioxide (chemical formula: ZrO2) is the main oxide of zirconium. Under normal conditions, it is white odorless and odorless crystal, and is hardly soluble in water, hydrochloric acid and dilute sulfuric acid. It usually contains a small amount of cerium oxide. It is chemically inert and has high melting point, high electrical resistivity, high refractive index and low thermal expansion coefficient, making it an important high temperature resistant material, ceramic insulating material and ceramic sunscreen. It is also the main raw material for artificial drilling. The band gap is approximately 5-7 eV. Properties: White heavy amorphous powder. Odorless. Tasteless. It is soluble in a mixture of 2 parts of sulfuric acid and 1 part of water, slightly soluble in hydrochloric acid and nitric acid, slowly dissolved in hydrofluoric acid, and almost insoluble in water. Irritating. The relative density is 5.85. Melting point 2680 °C. The boiling point is 4300 °C. Hardness is inferior to diamond. The zirconium-type ZrO2 is a yellow or brown monochromatic oblique crystal insoluble in water, hydrochloric acid and dilute sulfuric acid, and is soluble in hot concentrated hydrofluoric acid, nitric acid and sulfuric acid. Co-melting with a base to form a zirconate. The chemical properties are very stable. Used in the manufacture of advanced ceramics, enamels, refractory materials. It can be obtained by co-melting zircon and soda ash, leaching sodium zirconate with water, reacting with hydrochloric acid to form zirconium oxychloride, and calcining.
