Abstract: Disclosed is a connector contact material that has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance while maintaining the properties and insertion operability as a connector. The connector contact material has a coating film comprising the mixture of fluoric resin particles and fluoric oil on the surface of a substrate, wherein the thickness of the coating film is 0.2 to 0.5 ?m, and the proportion of the fluoric resin particles to the total amount of the fluoric resin particles and the fluoric oil in the coating film is 20% to 40% in mass, and thereby the connector contact material has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance.

Abstract: A process for producing silicon carbide whiskers by heating a react solid silicon-containing starting material and carbon-containing starting material in a reaction vessel, wherein a molding material, which is prepared by previously molding the silicon-cotaining starting material into a predetermined shape, and a powdery carbon starting material are heated to a predetermined reaction temperature under a hydrogen gas atmosphere. Silicon carbide whiskers which are linear with no bendings, long fiber length, high aspect ratio and low silicon dioxide impurity can be obtained at a high yield of greater than 90% based on silicon vaporized from the silicon-containing starting material.
