Abstract: The invention is a novel fullerene-added lead zirconate titanate and a method of producing the same, wherein zirconium alkoxide, titanium alkoxide and lead acetate are dissolved in an organic solvent with a stabilizer to form a colloidal solution or sol. The colloidal solution is added with fullerene, gelatinized, dried and fired at a relatively low temperature, for example, 400 to 500° C., whereby a perovskite phase can effectively be formed at a temperature lower than in conventional methods.

Abstract: A novel fine carbon wire includes a needle-like fullerene crystal having a smooth surface. The fine carbon wire can be produced by a method including the steps of (1) adding a solution containing the fullerene dissolved in a first solvent to a second solvent having less solvency for the fullerene than the first solvent; (2) forming a liquid-liquid interface between the solution and the second solvent; and (3) depositing a fine carbon wire at the liquid-liquid interface.

Abstract: A fullerene-dispersed ceramic is produced by an improved method in which C60 or like fullerene, and C16TMA 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.
