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.

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. A process for producing a ceramics-crystallized glass composite article having superior mechanical properties, thermal properties and mechanical workability, which comprises (1) mixing at least one ceramic material selected from powders, flakes and fibers of ceramics, a glass powder and an organometallic polymer in the optional presence of an organic solvent, said polymer being soluble in an organic solvent and having a skeleton comprising (a) titanoxane linkages －Ti－O－or zirconoxane linkage －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 linkage －Al－O－or both; and (2) either (i) molding the resulting mixture and then firing the molded article in an oxidizing atmosphere or (ii) molding and firing the resulting mixture simultaneously in an oxidizing atmosphere, thereby to bond said ceramic material by the glass at least partly crystallized.
