在批林整风、批林批孔和学习无产阶级专政理论运动的推动下,我所五室氮化硅小组的工人和科技人员,经过三年多的努力,初步研制成功了氮化硅工程陶瓷。氮化硅的原料丰富,加工方便,性能优异,用途广泛,经上海燎原化工厂及上海转子发动机会战组等单位试用,结果良好,证明它是一种值得大力推广的新型高温陶瓷材料。在 Under the impetus of rectifying winds, criticizing Lin and criticizing Confucianism and learning the theoretical campaign of proletarian dictatorship, the workers and technicians of our five-chamber silicon nitride team, after more than three years of efforts, have initially successfully developed the silicon nitride engineering ceramics . Silicon nitride rich in raw materials, processing convenience, excellent performance, wide range of uses, Shanghai Liaoyuan Chemical Plant and Shanghai Rotor Engine Battle Group and other units trial, the results show that it is a worthy of promotion of new high-temperature ceramic materials. in
