Silicon nitride iyo silicon carbide waa isku-xidhka isku-xidhka covalent-ka oo aad u xoog badan, waxay leeyihiin sifooyin jireed iyo kiimiko oo isku mid ah, silicon nitride oo lagu daray alaabada silicon carbide oo leh iska caabin heerkul sare, iska caabin daxaleed, iska caabin xirasho, iska caabin nabaad-guur, iska caabin oksaydh iyo taxane sifooyin aad u fiican. Silicon nitride iyo silicon carbide oo ah walxo heer sare ah oo ka soo horjeeda jawi kala duwan heerkulka isticmaalka caadiga ah wuxuu gaari karaa 1500 ℃ ama wax la mid ah, si ballaaran ayaa loogu isticmaalaa dhoobada, birta aan birta ahayn, birta iyo birta birta, birta budada, warshadaha kiimikada iyo warshadaha kale.
Nitride-ka Silicon oo lagu daray walxaha carbide-ka silicon iyo biraha aan birta ahayn ma soo galaan, waxayna leeyihiin sifooyin dahaadh wanaagsan, sidaa darteed waxaa si weyn loogu isticmaalaa habka wax soo saarka biraha aan birta ahayn sida aluminium, naxaasta iyo zinc, gaar ahaan agabka ugu habboon ee lagu soo saaro lebenka dahaarka derbiga dhinaca unugyada elektiroonigga ah.
