MANUFACTURING METHOD OF CERAMIC COMPOSITES WITH HIGH FRACTURE STRENGTH

摘要

PURPOSE: A manufacturing method of a ceramic composite with improved fracture strength is provided to obtain a ceramic composite with improved fracture strength by using alumina or aluminosilicate and graphene oxide. CONSTITUTION: A manufacturing method of a ceramic composite with improved fracture strength comprises a step of preparing a graphene oxide; a step of removing the graphene oxide from deionized water by using ultrasonic waves and forming a graphene oxide suspension; a step of adding aluminosilicate powder and a dispersant into deionized water and forming aluminosilicate slurry; a step of mixing the aluminosilicate slurry in the graphene oxide suspension; a step of drying and molding the mixture; and a step of sintering the molded product in a reduction atmosphere. The volume ratio of the graphene oxide and aluminosilicate is 0.1:99.5-5:95.
