摘要
This invention relates to a process for producing crystallized glass having superior mechanical properties and thermal properties, which comprises (1) coating glass in the form of a powder or molded article with an organometallic polymer, said polymer being soluble in an organic solvent and having a skeleton comprising (a) titanoxane linkages --Ti--O-- or zirconoxane linkages --Zr--O-- or both and (b) siloxane linkages --Si- -O-- in which most of the silicon atoms have as a side chain at least one organic group selected from alkyl and phenyl groups, and optionally (c) boroxane linkages --B--O-- or aluminoxane linkages --Al--O-- or both; and (2) firing the resulting polymer-coated glass in an oxidizing atmosphere to crystallize at least a part of the glass. This invention also pertains to a process for producing a ceramics-crystallized glass composite article using the aforesaid crystallized glass.
