SiC & Si3N4 Ceramic

氮化硅 Silicon nitride ceramics (Si3N4)

Silicon nitride da silicon carbide ne mai karfi covalent bond mahadi, da irin wannan jiki da kuma sinadaran Properties, silicon nitride hade da silicon carbide kayayyakin da high zafin jiki juriya, lalata juriya, sa juriya, yashwa juriya, hadawan abu da iskar shaka juriya da kuma jerin m Properties. Silicon nitride da silicon carbide a matsayin high-sa refractory kayan a daban-daban yanayi da al'ada amfani da zazzabi iya isa 1500 ℃ ko makamancin haka, yadu amfani a tukwane, non-ferrous karfe, baƙin ƙarfe da karfe karfe, foda karafa, sinadaran masana'antu da sauran masana'antu.

Silicon nitride hade da silicon carbide abu da kuma wadanda ba ferrous karafa ba su kutsawa, kuma yana da kyau rufi Properties, don haka shi ne yadu amfani a samar da wadanda ba ferrous karafa kamar aluminum, jan karfe da zinc, musamman ma manufa abu ga samar da electrolytic cell gefen bango rufi tubali.
