Title: Method of producing fullerene-dispersed ceramics

Abstract: A fullerene-dispersed ceramic is produced by an improved method in which C.sub.60 or like fullerene, and C.sub.16 TMA or like surfactant, are dissolved in a solution of metallic compound, such as zirconyl nitrate, to form a colloidal solution. A gel is formed from the colloidal solution by changing its hydrogen ion concentration. The gel is dried and subjected to heat treatment, to eliminate remaining solvent and surfactant, and thereby stably obtain the desired fullerene-dispersed ceramic powder in which the fullerene is uniformly dispersed and which is essentially free from carbon other than fullerene.
