ABSTRACT:
A method for preparing synthetic cristobalite comprises (1) preparing a mixture containing sources for an oxide of silicon and for an oxide of boron, a base of an alkali or alkaline earth metal or precursor of such base, a polyhydric alcohol, and water; and (2) maintaining the mixture at suitable reaction conditions to effect formulation of the cristobalite, said reaction conditions comprising a reaction temperature within the range of about 30.degree. C. to about 300.degree. C., a pressure of at least the vapor pressure of water at the reaction temperature, and a reaction time that is sufficient to effect crystallization.
