Ongera usubiremo Carbide ya Silicon (Rxsic, resic, RICS, R-sic). Gutangira ibikoresho fatizo ni kaburimbo ya silicon. Nta mfashanyigisho yo gukundwa ikoreshwa. Icyatsi kibisi gishyuha hejuru ya 2200ºc yo guhuza burundu. Ibikoresho bivamo bifite uburozi bugera kuri 25%, bugabanya imitungo yayo; Ariko, ibikoresho birashobora kuba byera cyane. Inzira irahagije.
Reaction yahujwe silicon carbide (RBIC). Gutangira ibikoresho fatizo ni silicon carbide wongeyeho karubone. Ibice bya Green noneho binjiye hamwe na clicon ya molten hejuru ya 1450ºC hamwe na reaction: sic + c + si -> sic. Ibikorwa bisanzwe bifite umubare munini wa silicon zirenze, zigabanya imitungo yacyo yo hejuru hamwe no kurwanya ruswa. Impinduka nto zingana zibaho mugihe cyibikorwa; Ariko, igice cya silicon akenshi gihari hejuru yigice cya nyuma. RBIC ya ZPC yemejwe ikoranabuhanga riharanira iterambere, ritanga imyanya iterwa no kwambara, amasahani, umurongo wa cyclone, no kwambara amakuru ya FGD, imiyoboro, imiyoboro, ibitugu, nibindi.
Nitride yahujwe silicon carbide (nbbic, NSIC). Ibikoresho fatizo nibikoresho bya silicon wongeyeho ifu ya silicon. Icyatsi kibisi kirasa mu kirere cya azote aho reaction sic + 3si + 2n2 -> sic + si3n4 ibaho. Ibikoresho byanyuma byerekana impinduka nkeya mugihe cyo gutunganya. Ibikoresho byerekana urwego runaka rwa porosity (mubisanzwe hafi 20%).
Kuyobora karbide ya silicon yahanaguye (ssic). Silicon carbide nintangiriro yibikoresho fatizo. Imfashanyigisho ni Boron wongeyeho karubone, kandi ubwigenge bubaho muburyo bukomeye bwa leta hejuru ya 2200ºC. Ubushyuhe bwayo buhebuje hamwe no kurwanya ruswa ni hejuru kubera kubura icyiciro cya kabiri cya kabiri ku mbibi z'ingano.
Pro Sposse Cenced Carbide ya Silicon (lissic). Silicon carbide nintangiriro yibikoresho fatizo. Imfashanyigisho ni Ytrium oxide wongeyeho aluminium oxide. Gucukura ibiboneka hejuru ya 2100ºc ukurikije ibiciro byihariye kandi bivamo icyiciro cya kabiri cya kabiri. Imiterere ya mashini isanzwe iruta ssic, ariko imitungo yo hejuru hamwe nimbaraga za ruswa ntabwo ari byiza.
Ashyushye ya Silicon Carbide (HPSIC). Ifu ya silicon Carbide ikoreshwa nkibikoresho fatizo. SIDACERS SIDA muri rusange Boron wongeyeho karubone cyangwa Yttrium oxide wongeyeho aluminium oxide. Gucuranga neza biba ngombwa mugukoresha umuvuduko ukabije nubushyuhe imbere ya grapite ipfa cavit. Imiterere nisahani yoroshye. Umubare munini wibintu byinteruro birashobora gukoreshwa. Ibikoresho bya mashini yibikoresho bishyushye bikoreshwa nkibishishwa binyuranyije nindi nzira ugereranije. Imitungo y'amashanyarazi irashobora guhindurwa n'impinduka muri sinisiyo.
Cvd carbide ya silicon (cvdic). Ibi bikoresho byashyizweho na gahunda yo kubyutsa imiti (CVD) irimo reaction: Ch3sicl3 -> sic + 3hcl. Imyitwarire ikorwa munsi yikirere cya H2 hamwe na sic ishyirwa kumurongo. Inzira bivamo ibintu byera cyane; Ariko, gusa amasahano yoroshye. Inzira ihenze cyane kubera ibihe byimyitwarire buhoro.
Imyuka ya chimique igizwe na chicon carbide (cVCSic). Iyi mikorere itangirana nubushushanyo mbonera bukoreshwa muburyo bugera kuri net kumurongo mubi. Guhinduranya ingingo igishushanyo mbonera cyigishushanyo mbonera cyimpanuka kivanze-leta kugirango itange polycrystalline, stochiometricial sic. Iki gikorwa kigenzurwa cyane kituma ibishushanyo bitoroshye bikorerwa muburyo bwahinduwe rwose ni impengamico ihanitse ibiranga kandi isukuye. Inzira yo guhindura igabanya igihe gisanzwe cyo kubyara no kugabanya ibiciro hejuru yubundi buryo. * Inkomoko (usibye aho wabivuze): Ceradyne Inc., Costa Mesa, Calif.
