Zirconium dioxide (chemical formula: ZrO2) is the main oxide of zirconium, usually white odorless, odorless and tasteless crystal, difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It usually contains a small amount of hafnium dioxide. The chemical properties are not active, and the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient make it an important high temperature resistant material, ceramic insulation material and ceramic shader. It is also the main raw material of artificial drilling, and the energy band gap is about 5-7ev. Used for making zirconium and zirconium compounds, firebrick and crucible, high frequency ceramics, grinding materials, ceramic pigments and zirconates, etc.

The definition of zirconium dioxide, or zirconium dioxide, requires a certain material basis. It refers to a crystal made of thousands or tens of thousands of cells per grain. Of course, this explanation is a mouthful, but the characteristics of microcrystalline ceramics are good, with high thermal conductivity and thermal expansion coefficient close to zero, no water absorption, good insulation performance, dense and even structure, impact resistance, wear resistance and corrosion resistance. Simply put, it is resistant to falling, wear-resistant, and does not affect heat dissipation and beauty.
