The present invention aims to provide a fluororesin-aluminum oxide mixed dispersion wherein both fluororesin particle and aluminum oxide particle uniformly float and disperse in an aqueous solvent. The fluororesin-aluminum oxide mixed dispersion is obtained by mixing aqueous dispersion of fluororesin particle and aluminum oxide particle sol, wherein both the fluororesin particle and the aluminum oxide particle float and disperse, and wherein the dispersion state is stably maintained for three days or more. A solid product obtained by evaporation and scattering of the solvent from the above-described fluororesin-aluminum oxide mixed dispersion has a heat resistance of not less than 330° C.
A fluororesin-aluminum oxide mixed dispersion obtained by mixing an aqueous dispersion of fluororesin particle and an aluminum oxide particle sol, wherein both the fluororesin particle and the aluminum oxide particle float and disperse, and wherein the dispersion state is stably maintained for three or more days, wherein the aluminum oxide particle in said aluminum oxide particle sol is a hydroxyl (OH) group containing aluminum oxide particle.
