I-Silicon Carbide itholakala ngezindlela ezimbili, i-rection bonded ne-sintered. Ukuze uthole ulwazi olwengeziwe ngalezi zinqubo ezimbili sicela usithumele i-imeyili ku[i-imeyili ivikelwe]
Zombili izinto ezisetshenziswayo zi-ultra-hard futhi zinokusebenza okuphezulu kwe-thermal. Lokhu kuholele ekutheni i-silicon carbide isetshenziswe ekufakeni nasekufakweni kophawu olujikelezayo lapho ubulukhuni obukhulayo kanye nokuhamba kuthuthukisa ukusebenza kophawu nokusebenza.
I-Reaction bonded silicon carbide (RBSC) inendawo enhle emazingeni okushisa aphakeme futhi ingasetshenziswa ezinhlelweni eziphikisayo.
Izinto ze-silicon carbide zibonisa ukuguguleka okuhle nokumelana nokuguguleka, lezi zakhiwo zingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezifana nama-nozzles of spray, ama-shot blast nozzles kanye nezingxenye zesiphepho.
Izinzuzo Ezibalulekile kanye Nezakhiwo Ze-Silicon Carbide Ceramics:
l High conductivity ezishisayo
l I-coefficient ephansi yokwandisa okushisayo
l Ukumelana nokushaqeka okushisayo okuvelele
l Ukuqina okwedlulele
l I-semiconductor
l Inkomba ye-refractive inkulu kunedayimane
Ukuze uthole imininingwane eyengeziwe nge-Silicon Carbide Ceramics sicela usithumele i-imeyili ku[i-imeyili ivikelwe]
I-Silicon Carbide Production
I-Silicon Carbide itholakala kumpuphu noma okusanhlamvu, ekhiqizwa ekuncishisweni kwekhabhoni ye-silica. Ikhiqizwa njengempushana ecolekile noma inqwaba enkulu eboshiwe, bese igaywa. Ukuhlanza (ukukhipha i-silica) igezwa nge-hydrofluoric acid.
Kunezindlela ezintathu eziyinhloko zokwenza umkhiqizo wezohwebo. Indlela yokuqala iwukuxuba i-silicon carbide powder nenye into efana nengilazi noma insimbi, lokhu bese kuphathwa ukuze kuvunyelwe isigaba sesibili ukuthi sihlangane.
Enye indlela ukuxuba i-powder ne-carbon noma i-silicon powder powder, okube sekuhlanganiswe ukusabela.
Ekugcineni i-silicon carbide powder ingaxutshwa futhi ifakwe emanzini ngokufaka i-boron carbide noma olunye usizo lwe-sintering ukuze yenze izitsha zobumba eziqine kakhulu. Kumele kuqashelwe ukuthi indlela ngayinye ifanelana nezinhlelo zokusebenza ezahlukene.
Ukuze uthole ulwazi olwengeziwe mayelana ne-Reaction Bonded Silicon Carbide Ceramics sicela usithumele i-imeyili ku[i-imeyili ivikelwe]
