    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.

    Abstract: A molded part of a ceramic material derived from polymers includes a composite body of a single-phase or multi-phase, amorphous, partially crystalline or crystalline matrix of silicon carbide (SiC), silicon nitride (Si3N4), silicon dioxide (SiO2) or mixtures thereof. The matrix contains graphite inclusions and the density of the ceramic material is at least 85% of the theoretical value. The molded part is produced by subjecting a mixture formed of a polymer component in an amount of 30 to 80 wt. % referred to the total weight of the mixture, fillers in an amount of 0 to 30 wt. % and graphite in an amount of 10 to 70 wt. %, to a forming process with heating to effect crosslinking of the polymer components, followed by a pyrolysis process. In particular, the molded parts are produced from polymers of the group including polysilanes, polysiloxanes, polysilazanes or polycarbosilanes. A process for producing ceramic molded parts and a sliding element having a molded part are also provided.
