SiC & Si3N4 Ceramic

氮化硅 dhoobada Silicon nitride (Si3N4)

Silicon nitride iyo silikoon carbide waa xeryahooda curaarta covalent aad u xoog badan, waxay leeyihiin sifooyin jidh iyo kiimiko la mid ah, silicon nitride oo ay weheliso alaabta silikoon carbide leh caabbinta heerkulka sare, iska caabin daxalka, xidhashada caabbinta, caabbinta nabaad guurka, caabbinta oksidation iyo taxane ah sifooyin aad u fiican. Silicon nitride iyo silikoon carbide sida walxaha refractory-sare ee jawiga kala duwan heerkulka isticmaalka caadiga ah wuxuu gaari karaa 1500 ℃ ama wax ka badan, oo si ballaaran loogu isticmaalo dhoobada, birta aan birta ahayn, birta iyo birta birta, birta budada, warshadaha kiimikada iyo warshadaha kale.

Silikon nitride oo lagu daray walxaha silikoon carbide iyo biraha non-ferrous ma galaan, oo waxay leedahay sifooyin dahaarka wanaagsan, sidaas darteed waxaa si ballaaran loo isticmaalaa in habka wax soo saarka ee biraha non-ferrous sida aluminium, copper iyo zinc, gaar ahaan qalabka ugu fiican ee wax soo saarka ee leben dahaarka derbiga dhinaca unugyada electrolytic.
