ZIRCONIUM DIOXIDE POWDER AND ZIRCONIUM DIOXIDE DISPERSION

摘要

Zirconium dioxide powder in the form of aggregated primary particles, having a BET surface area of 30 to 150 m2/g and a Berger whiteness of at least 88%. It is prepared by atomizing a solution which comprises an organic zirconium compound and mixing it with a combustion gas and air and allowing the mixture to burn in a flame into a reaction chamber surrounded by a casing, where the temperature in the reaction chamber and along the side of the wall of the casing facing the reaction chamber is at least 500° C. Dispersion comprising the zirconium dioxide powder. Use of the zirconium dioxide powder and of the dispersion for producing ceramics.
