Silicon nitride uye silicon carbide yakasimba kwazvo covalent bond komisheni, ane akafanana emuviri uye makemikari zvivakwa, silicon nitride yakasanganiswa nesilicon carbide zvigadzirwa zvine tembiricha inodzivirira, corrosion resistance, kupfeka kusamira, erosion resistance, oxidation resistance uye zvakatevedzana zvemhando yepamusoro. Silicon nitride uye silicon carbide seyepamusoro-giredhi refractory zvinhu mumhepo dzakasiyana siyana tembiricha yekushandiswa inogona kusvika 1500 ℃ kana zvakadaro, inoshandiswa zvakanyanya muceramics, non-ferrous metallurgy, iron nesimbi metallurgy, poda metallurgy, indasitiri yemakemikari uye mamwe maindasitiri.
Silicon nitride yakasanganiswa nesilicon carbide zvinhu uye isiri-ferrous simbi haipindi, uye ine yakanaka yekudzivirira zvivakwa, saka inoshandiswa zvakanyanya mukugadzira simbi dzisina-ferrous sealuminium, mhangura uye zinc, kunyanya iyo yakanakira zvinhu. kugadzirwa kwe electrolytic cell side wall lining zvidhinha.
