Zirconium Oxide

Zirconium Oxide

CAS #: 1314-23-4
Linear Formula: ZrO2
EC No.: 215-227-2

Product Details

Zirconium Oxide is a white powder,  molecular formula ZrO2, insoluble in water, hydrochloric acid and dilute sulfuric acid. Hafnium dioxide is usually contained in a small amount, which is chemically inert and has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important heat resistant material, ceramic insulating material and ceramic sunshade agent, and also the main raw material for artificial drilling. The band gap is about 5-7ev.

It's mainly used for making metal zirconium and zirconium compounds, and the crucible refractory brick, high-frequency ceramic and grinding materials, ceramic pigment and zirconium salts, etc., at the same time can also be used for piezoelectric ceramics, daily-use ceramics, refractory materials and precious metals smelting with zirconium brick, zirconium tube, crucible, production of steel and non-ferrous metals, optical glass and zirconium dioxide fiber. It is also used in ceramic pigments, electrostatic coatings and baking paints. Together with yttrium can be used to manufacture the light source in an infrared spectrometer, thick film circuit capacitor material, piezoelectric crystal transducer, etc.
