Silicon nitride le silicon carbide ke metsoako e matla ea covalent bond, e na le thepa e tšoanang ea 'mele le lik'hemik'hale, silicon nitride e kopantsoeng le lihlahisoa tsa silicon carbide tse nang le mocheso o phahameng oa mocheso, ho hanyetsa kutu, ho hanyetsa ho roala, ho hanyetsa khoholeho, khanyetso ea oxidation le letoto la thepa e babatsehang. Silicon nitride le silicon carbide e le lisebelisoa tsa boemo bo phahameng ba refractory libakeng tse fapaneng mocheso o tloaelehileng oa ts'ebeliso o ka fihla ho 1500 ℃ kapa ho feta, o sebelisoa haholo ka lirafshoa, tšepe e se nang ferrous, metallurgy ea tšepe le tšepe, metallurgy ea phofo, indasteri ea lik'hemik'hale le liindasteri tse ling.
Silicon nitride e kopantsoeng le lisebelisoa tsa silicon carbide le litšepe tse se nang ferrous ha li kenelle, 'me li na le thepa e ntle ea ho kenya letsoho, ka hona e sebelisoa haholo ts'ebetsong ea tlhahiso ea litšepe tse se nang ferrous tse kang aluminium, koporo le zinki, haholo-holo thepa e loketseng bakeng sa tlhahiso ea litene tsa lerako la li-electrolytic cell side.
