Ithonya le i-silicon carbide (SiC) kuzakhiwo zama-castable

⑴ Njengoba i-SiC ngokwayo ivimbela amanzi, akulula ukumanziswa, futhi akulula ukwenza ungqimba lwefilimu yamanzi, futhi ukusetshenziswa kwamanzi okuphonswa kuyanda. Ngakho-ke, ukuphakama kokuqukethwe kwe-SiC, ukungasebenzi kahle nokusebenza kahle kwe-castable, futhi amandla abandayo e-flexural azokwehla.

⑵ Njengoba ukuminyana kwenqwaba ye-SiC (2.6~2.8g/cm3) kukhulu kunokuminyana kwezithako zobumba (2.2~2.4g/cm3), okuqukethwe kwe-SiC okwengeziwe, kuba mkhulu ukuminyana kwevolumu yento. Lapho izinga lokushisa likhuphuka futhi okuqukethwe kwe-SiC kuphezulu, ukuminyana kwevolumu kuzokhuphuka ngezinga elithile. Okuqukethwe kwe-SiC kubonisa inani elibi lomthelela woshintsho lomugqa wezinto ezibonakalayo.

⑶ Okuqukethwe kwe-SiC kunenzuzo emandleni okuphonswa, ikakhulukazi kumazinga okushisa aphezulu (1100°C). Ikakhulukazi lapho usayizi wezinhlayiyana ze-SiC zingama-mesh angu-150, awukwazi ukufakwa nge-oxidized ngokuphelele, futhi ezinye izikhala zakhiwa eduze kwezinhlayiya ze-SiC, okuthuthukisa ukumelana nokushaqeka okushisayo namandla okuphonswa. I-SiC engenalutho futhi isebenza njengokuqinisa izinhlayiyana.

⑷ Ukwanda kokuqukethwe kwe-SiC, kuba ngcono ukusebenza kwento emelene nokusulwa kwesikhumba.

⑸ Ukwanda kokuqukethwe kwe-SiC, kuba ngcono ukumelana ne-alkali.
