▎ 摘　　要

NOVELTY - Silicon oxide-based graphene ceramic ball bearing comprises 77-96.4 wt.% quartz glass powder, 3-15 wt.% mullite powder, 0.5-3 wt.% cristobalite powder, 0.1-5 wt.% graphene powder and 10-24 wt.% plasticizer. USE - Used as silicon oxide-based graphene ceramic ball bearing. ADVANTAGE - The bearing: has excellent mechanical properties, high-temperature deformation resistance and high-temperature strength, improved fluidity, molding rate and strength, high pressing qualification rate and high sintering qualification rate and strong impact resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing silicon oxide-based graphene ceramic ball bearing comprising (i) mixing silica glass powder, mullite powder, cristobalite powder, and graphene powder into powder, adding the powder into a three-dimensional mixer to obtain ceramic powder with uniform mixing and uniform composition, (ii) adding paraffin, beeswax, polyethylene based on proportion into vacuum mixer and heating until it melts, stirring uniformly, adding graphene powder, stirring for 12 hours and vacuuming for 30 minutes, allowing to stand for 10 minutes, discharging and cooling to obtain the plasticizer, (iii) adding obtained plasticizer into vacuum blender, heating to melt, adding the obtained ceramic powder, stirring uniformly for 24 hours, evacuating for 2 hours and terminating stirring to obtain ceramic core slurry, (iv) adding the ceramic core slurry into the ceramic core injection machine, pressing the ceramic core slurry into the required mold when the temperature of the material matches the temperature of the pressure injection process to obtain wet ceramic core, and (v) adding the wet ceramic core into the beaker equipped with alumina filler, then adding burning bowl into the box type calcining furnace, heating at 400 degrees C at a rate of 0.1-3 degrees C/minute, calcining at 900-1000 degrees C at a rate of 0.5-5 degrees C/minute, further heating at 1160-1250 degrees C at a rate of 2-5 degrees C/minute, allowing to stand for 2-8 hours, cooling to 900-1000 degrees C at the rate of 0.5-1 degrees C/minute, then cooling to room temperature to obtain final product.
