NOVELTY - High-toughness ceramic thin plate comprises 40-50 pts. wt. cordierite, 20-30 pts. wt. silicon carbide, 10-20 pts. wt. graphene fibers, 10-20 pts. wt. sepiolite fibers, 5-10 pts. wt. modified phosphor graphite, 2-6 pts. wt. nanowire composite powder, 1-3 pts. wt. hybrid whisker body and 1-5 pts. wt. magnesium oxide sintering agent. USE - High toughness ceramic thin plate. ADVANTAGE - The high-toughness ceramic thin plate has excellent toughness property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a high-toughness ceramic thin plate, which involves: (1) stirring and mixing cordierite, silicon carbide, graphene fiber, sepiolite fiber, modified phosphorus flake graphite, nanowire composite powder, hybrid whisker body, and magnesium oxide sintering agent until sufficient in turn to obtain a material to be sintered; (2) pressing and forming material to be sintered and placing in a sintering furnace for sintering treatment, the sintering temperature is 1350 degrees Celsius, and the sintering is completed to obtain a high-toughness ceramic sheet.
