摘要： 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.

摘要： A method of producing coal briquette at a low energy cost by saving heating step or drying step for fine coal, which comprises adding and mixing from 1 to 10 mass parts of powdery starch to a coal having 15 mass % or more of water content and comprising 50 mass % or more of particles with grain size of 5 mm or less to form 100 mass parts of a mixture, and coating the surface of the briquette product with 0.1 to 5 mass parts of a heavy oil component simultaneously with or after pressure briquetting the mixture by a double roll briquetting machine in which concaves are formed on the roll surface, as well as coal briquette which is inexpensive and has high strength and high waterproof.
