Zirconium Dioxide Powder CAS 1314-23-4 For Ceramic

Products Description

The substance corresponding to CAS No. 1314 - 23 - 4 is Zirconium Dioxide, also known as Zirconium (IV) oxide or Zirconium Oxide, which plays an important role in the fields of chemical engineering and materials science. Its molecular formula is O₂Zr, its molecular weight is 123.22, and its EINECS No. is 215 - 227 - 2.
Zirconium Dioxide usually appears as white odorless crystals, but also as a white amorphous powder. It has a very high melting point of 2700℃, a boiling point of 5000℃, a density of 5.89g/mL (at 25℃), and a flash point of 5000℃. Zirconium oxide is insoluble in water, hydrochloric acid and dilute sulfuric acid, but soluble in hot concentrated hydrofluoric acid and sulfuric acid. From the chemical properties, it is chemically inactive and belongs to weakly acidic oxides. It has the characteristics of high resistivity, high refractive index (2.2) and low thermal expansion coefficient. The dielectric constant is 12.5 (0.0℃) and the pH value is between 4 and 5.

Basic Info

Production method

The most common method is the thermal decomposition of zirconium oxychloride, that is, zircon and caustic soda are melted at 650℃, hot water is used to leach the melt to separate silicon from sodium zirconate in the form of sodium silicate, and then treated with sulfuric acid to obtain a zirconium sulfate solution. After removing impurities, ammonia water is added to precipitate zirconium hydroxide, and hydrochloric acid is added to dissolve the zirconium hydroxide to obtain zirconium oxychloride. After evaporation and concentration, cooling and crystallization, crushing, and roasting, the finished zirconium dioxide is obtained.

Uses

In the field of ceramics, Zirconium Dioxide is an important raw material for the production of structural ceramics, functional ceramics and daily - use ceramics. It is also utilized in the production of products like ceramic knives. Moreover, it can be used as a raw material for ceramic pigments and zirconates.
Moreover, in the field of refractory materials, Zirconium Dioxide serves as a crucial material for fabricating components of large - scale glass tank kilns. It is employed in the production of refractory bricks, crucibles, zirconia refractory fibers, zirconia hollow balls, and various high - grade insulating bricks.
Furthermore, in the electronics field, it is used to make piezoelectric ceramic products and electronic ceramics, and has applications in thick - film circuit capacitor materials, micro - integrated circuit boards, etc.
