Abstract ZrO2-transformation-toughened glass-ceramics have been prepared by the sol-gel process from either colloidal gels (CG) or polymeric gels from alkoxides (PG), using, in the latest method, a different catalyst (acid, basic and without catalyst), and different compositions in the ZrO2·SiO2 system (free ZrO2 included). The different methods of synthesis of tetragonal zirconia in SiO2 matrix were compared in order to obtain thermal stability, and a high amount of stabilized tetragonal zirconia. The effect of catalyst, hydrolysis time, chemical composition, critical particle size in ZrO2(t)→ZrO2(m) transformation, the doping with vanadium on the ZrO2(t) stability in SiO2 matrix and Vickers microhardness of samples have also been studied.
