1. Isetshenziswa njenge-ejenti yokukhulula isikhunta se-polycrystalline silicon kanye ne-crystal crystal quartz crucible eyodwa.Vimbela udonga lwangaphakathi lwe-crucible ukuthi lunganamatheli ezintweni ze-silicon ezincibilikisiwe, lula ukudilizwa, futhi ngesikhathi esifanayo usebenze njengesendlalelo sokuvimbela ukuze uqinisekise ubumsulwa bezinto ze-silicon.I-solar-grade silicon nitride powder isetshenziswa njenge-ejenti yokukhulula isikhunta futhi ifuthwe endaweni engaphakathi ye-polysilicon ingot crucible, okuwumkhiqizo obalulekile wokukhiqiza ingot ye-polysilicon.

2. I-silicon nitride isetshenziswa njengento ephikisayo yezinga eliphezulu.Isibonelo, i-SI3N4-SIC refractory isetshenziswa emzimbeni wesithando somlilo nezinye izingxenye ngokubambisana ne-sic;uma isetshenziswa ihlanganiswe ne-BN njengento ye-SI3N4-BN, isetshenziswa endandeni yokuhlukanisa evundlile eqhubekayo.
