Title: GLASS CERAMIC COMPOSITE FOR CHEMICAL STRENGTHENING, CHEMICALLY STRENGTHENED GLASS CERAMIC COMPOSITE, AND METHOD FOR PRODUCING SAME
Abstract:
Provided are: a glass ceramic composite for chemical strengthening, said glass ceramic composite having exceptional machinability and being capable of imparting high strength; a chemically strengthened glass ceramic composite in which the glass ceramic composite is used; and a method for producing the chemically strengthened glass ceramic composite. A glass ceramic composite for chemical strengthening obtained by dispersing mica powder in a glass matrix, wherein, in the glass ceramic composite for chemical strengthening, the glass that constitutes the glass matrix includes the following, expressed in terms of the molar percentage of oxides: 40 to 65% of SiO2, more than 8.0% to no more than 21.0% of Al2O3, more than 5% to 40% of B2O3, a total of 5 to 23% of one or more species selected from Li2O and Na2O, and 0 to less than 2% of an alkaline earth metal oxide.
