Product Description
99.95% ultrafine zirconia ZrO2 for Ceramic glaze
Name: Zirconium Dioxide
Molecular Formula: ZrO2
Molecular Weight: 123.22
Property: White powder
Zircoium dioxide is white heavy amorphous powder. Odorless and tasteless. There are three crystal forms: monoclinic, cubic, and tetragonal. Relative density 5.85, melting point 2680 ºC, boiling point 4300 ºC, refractive index 2.2. Form square crystals above 1100 ºC and cubic crystals above 1900 ºC. Can dissolve in sulfuric acid, hydrofluoric acid, hot hydrochloric acid, and nitric acid, as well as in molten potassium bisulfate. Fusing with sodium carbonate to form sodium zirconate, sodium zirconate hydrolyzes into sodium hydroxide and almost insoluble zirconium hydroxide when it comes into contact with water.
Product Parameters
1. High purity ultrafine zirconia can be used as a stabilizer for incandescent lamps. It has far-infrared electrical properties, which save energy and improve the life of the lamp tube. It has been widely used.
2. In addition, zirconia has high refractive index and high temperature resistance, and can be used as enamel, refractory material, and electrical insulation material.
3. It can also be used as X-ray photography, grinding materials, optical glass, optical fibers, micro integrated circuit boards, high-power microscopes, and magnifying glass lenses.
4. It is also a material for producing ceramic tiles and sanitary ceramics, which can improve the toughness of ceramics and prevent ceramic cracking.
