中国科学院上海硅酸盐化学与工学研究所的氮化硅小组,试制成功一种新型耐腐蚀、耐磨工业陶瓷——反应烧结氮化硅。反应烧结氮化硅是以普通的硅粉作原料,用一般陶瓷成型的方法制成素坯,在通氮气的炉子中将素坯进行初步氮化。经初步氮化的坯体,可在各种机床上进行车、钻、刨、铣等 A new type of corrosion-resistant and wear-resistant industrial ceramic-reactively sintered silicon nitride has been trial-produced successfully in the silicon nitride group of the Shanghai Institute of Ceramics Chemistry and Engineering, Chinese Academy of Sciences. Reaction sintering silicon nitride is ordinary silicon powder as raw material, with the general method of forming ceramic green body biscuit, the nitrogen in the furnace through the initial nitriding nitriding. After the initial nitriding of the green body, in a variety of machine tools on the car, drilling, planing, milling and so on
