▎ 摘　　要

NOVELTY - Silicon carbide composite material comprises 70-80 wt.% silicon carbide powder, 3-15 wt.% metal powder, 1-5 wt.% graphene, 2-10 wt.% viscous caking agent, and 10-20 wt.% water. USE - Silicon carbide composite material. ADVANTAGE - The silicon carbide composite material has low firing temperature, energy saving, simple production process, low production cost, has long service life, high compressive strength, good thermal shock resistance and good oxidation resistance, and has wide economic and social values. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a silicon carbide composite material, which involves: (A) weighing silicon carbide powder, metal powder, and graphene in a powder mixer and mixing to obtain mixed powder, placing in a ball mill and stirring for 1-2 hours; (B) weighing the binder in parts by weight and dissolving in water to obtain a mixed binder; (C) adding mixed binder to the mixed powder and mixing for 0.5-2 hours to obtain the mixture; (D) placing mixture in a hydraulic press for molding treatment to obtain a blank; and (E) placing blank in a non-oxidizing atmosphere sintering furnace and calcining at 700-900 degrees C for 1-3 hours, cooling to room temperature with the furnace to obtain carbonization Silicon composite material.
