Zirconium Dioxide

　　Zirconia Product Introduction: Chemical Molecular Formula ZrO2　　1. Property: White particles (powder), insoluble in water, hydrochloric acid, and dilute sulfuric acid. It is chemically inactive, with high melting point, high resistivity, high refractive index, and low thermal expansion coefficient, making it an important high-temperature resistant material, ceramic insulation material, and ceramic light shielding agent, as well as the main raw material for artificial drilling.　　2. Usage: Mainly used for zirconium bricks, zirconium tubes, crucibles, etc. for piezoelectric ceramic products, daily ceramics, refractory materials, and precious metal melting. It is also used in the production of steel and non-ferrous metals, optical glass, and zirconia fibers. Can be used as a high-temperature insulation material with high *　　Material.　　3. Packaging: 25kg woven bag, lined with plastic bag.　　4. Product specifications: High purity zirconia 99.9%, ordinary zirconia 99.5%, specific meter and particle size can be controlled according to customer requirements.
