Silicon nitride is a gray ceramic with high fracture toughness, excellent heat shock resistance, and relatively impenetrable properties to molten metals.<\/p>\n

Using these characteristics, it is applied to internal combustion engine parts such as automobile engine parts, welding machine blowpipe nozzles, etc., especially parts that need to be used in harsh environments such as overheating.<\/p>\n

With its high wear resistance and high mechanical strength, its applications in bearing roller parts, rotating shaft bearings and semiconductor production equipment spare parts are constantly expanding.<\/p>\n

Le ceramiche di nitruro di silicio hanno un basso coefficiente di espansione termica e un'elevata conducibilit\u00e0 termica, quindi hanno un'eccellente resistenza agli shock termici. Il nitruro di silicio sinterizzato a caldo non si romper\u00e0 dopo essere stato riscaldato a 1000 \u2103 e messo in acqua fredda. A una temperatura non troppo alta, il nitruro di silicio ha una resistenza ad alta resistenza e impatto, ma sopra i 1200 \u2103 saranno danneggiati con la crescita del tempo di utilizzo, in modo che la sua resistenza sia ridotta, pi\u00f9 inclini a danni da fatica superiori a 1450 \u2103, quindi l'uso della temperatura SI3N4 generalmente non supera i 1300 \u2103.<\/p>\n
