▎ 摘  要

NOVELTY - Composite ceramic microsphere comprises a zirconium source, graphene oxide, a gel auxiliary agent and a chelating auxiliary agent. USE - Composite ceramic microsphere. ADVANTAGE - The composite ceramic microsphere is intact and crack-free zirconium composite microsphere without addition of metal ion additive, has good mechanical property, and provides possibility for subsequent application in fuel inert substrate, electrical and magnetic field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite ceramic microsphere, which involves: (A) stirring, dissolving and cooling the zirconium source to obtain the first solution; (B) mixing and dissolving gel auxiliary agent and chelating auxiliary agent, and cooling it to obtain a second solution; (C) mixing and dispersing graphene oxide with second solution, mixing and cooling it with the first solution to obtain a glue solution; (D) dropping glue solution into hot silicone oil to obtain microspheres after aging; and (E) washing, drying and heat-treating obtained microspheres in a nitrogen atmosphere to obtain composite ceramic microsphere.
