SYNTHETISCH AMORF ZIRKONIUM-GEBONDEN SILICAAT EN WERKWIJZE TER BEREIDING DAARVAN.

摘要

The present invention provides a synthetic amorphous zirconium-bonded silicate obtained by reacting, as main starting materials, a water-soluble alkali-metal silicate with an inorganic zirconyl salt and a mineral acid, in which zirconium is bonded to silica at the ratio of ZrO2 to SiO2 being 0.1 to 10 weight percent, which silicate is useful as a dentifrice base material and also as a filler for rubber.
