Thermally split zirconium silicate, method of its production and use
Thermally split zirconium silicate is produced such that the crystalline zirconium dioxide embedded in an amorphous silica phase exhibits an average grain or particle size (d50 value) in a range of 0.5 mu m to 3.0 mu m and a specific surface (BET) in a range of 3 to 15 m2/g. The zirconium dioxide pr...

| description | Thermally split zirconium silicate is produced such that the crystalline zirconium dioxide embedded in an amorphous silica phase exhibits an average grain or particle size (d50 value) in a range of 0.5 mu m to 3.0 mu m and a specific surface (BET) in a range of 3 to 15 m2/g. The zirconium dioxide produced by this method is particularly suited for the production of zirconium silicate pigments with improved color characteristics. The thermally split zirconium silicate is also particularly well suited for processes used in the obtention of zirconium dioxide. The method of producing the thermally split zirconium silicate includes melting zirconium silicate in an induction melting furnace and cooling off a free falling stream of melt by blowing on it with a gas and/or spraying it with water. |
