Karubide ya Silicone yongeye gukoreshwa (RXSIC, ReSIC, RSIC, R-SIC). Ibikoresho fatizo byo gutangira ni karubide ya silicon. Nta bikoresho bifasha mu kongera ubucucike bikoreshwa. Uduce tw'icyatsi kibisi dushyuha kugeza kuri 2200ºC kugira ngo duhuzwe burundu. Ibikoresho bivamo bifite porosity ya 25%, ibi bikaba bigabanya imiterere yabyo; icyakora, ibikoresho bishobora kuba byiza cyane. Uburyo buhendutse cyane.
Karubide ya Silicon Ihuza Ibikoresho (RBSIC). Ibikoresho fatizo byo gutangira ni karubide ya silicon hamwe na karuboni. Igice cy'icyatsi kibisi gishyirwamo karubide ishongeshejwe hejuru ya 1450ºC hamwe n'ibisubizo: SiC + C + Si -> SiC. Imiterere mito muri rusange ifite ingano ya silicon irenze, ibi bikaba bigabanya imiterere yayo y'ubushyuhe bwinshi no kudakira ingese. Impinduka nke mu ngero ziba mu gihe cy'igikorwa; icyakora, urwego rwa silicon rukunze kugaragara ku buso bw'igice cya nyuma. ZPC RBSiC zakoreshejwe mu ikoranabuhanga rigezweho, ritanga utwenda two kwirinda kwangirika, amasafuriya, amatafari, utwenda twa cyclone, ibice, ibice bidahuye, n'iminwa ya FGD yo kwirinda kwangirika no kudakira ingese, umuyoboro w'ubushyuhe, imiyoboro, imiyoboro, n'ibindi.
Karubide ya Silikoni Iboheshejwe na Nitride (NBSIC, NSIC). Ibikoresho fatizo byo gutangira ni karubide ya silikoni hamwe n'ifu ya silikoni. Ifu y'icyatsi kibisi ikoreshwa mu kirere cya azote aho habaho reaction SiC + 3Si + 2N2 -> SiC + Si3N4. Ibikoresho bya nyuma bigaragaza impinduka nto mu gihe cyo gutunganya. Ibikoresho bigaragaza urwego runaka rw'ubushyuhe (ubusanzwe hafi 20%).
Karuboni ya Silikoni Idahinduka (SSIC). Karuboni ya Silikoni ni yo itangira gukoreshwa. Ifasha mu kongera imbaraga ni boroni hamwe na karuboni, kandi kwiyongera kw'imbaraga bibaho bitewe n'uburyo bwo gukora ibintu bitagira ingaruka ku bushyuhe buri hejuru ya 2200ºC. Imiterere yayo y'ubushyuhe bwinshi no kurwanya ingese ni byiza cyane kubera ko nta gice cya kabiri cy'ikirahure ku mbibi z'ingano.
Karubide ya Silikoni Ikozwe mu Gice cy'Amazi (LSSIC). Karubide ya Silikoni ni yo itangira gukoreshwa. Ibifasha mu gukurura ni yttrium oxyde hamwe na aluminiyumu oxyde. Gukurura biba hejuru ya 2100ºC binyuze mu buryo bw'amazi kandi bigatanga icyiciro cya kabiri cy'ikirahure. Imiterere ya mekanike muri rusange iruta SSIC, ariko imiterere y'ubushyuhe bwinshi n'ubudahangarwa bwo kwangirika ntabwo ari byiza cyane.
Karubide ya Silicon ishyushye (HPSIC). Ifu ya karubide ya silicon ikoreshwa nk'ibikoresho fatizo byo gutangira. Ibikoresho byo kongera imbaraga muri rusange ni boron hamwe na karuboni cyangwa yttrium oxide hamwe na aluminiyumu oxide. Gushyira imbaraga mu kirere bibaho binyuze mu gushyira igitutu n'ubushyuhe bya mashini icyarimwe mu mwobo wa graphite. Imiterere ni amasahani yoroshye. Ingano nto y'ibikoresho byo gutwika ishobora gukoreshwa. Imiterere ya mashini y'ibikoresho bishyushye ikoreshwa nk'ishingiro ry'uko izindi nzira zigereranywa. Imiterere y'amashanyarazi ishobora guhinduka bitewe n'impinduka mu bikoresho byo kongera imbaraga.
CVD Silicon Carbide (CVDSIC). Iki gikoresho kigizwe n'uburyo bwo gushyira umwuka mu kirere (CVD) burimo: CH3SiCl3 -> SiC + 3HCl. Uburyo bwo gukora ibintu bukorerwa munsi y'ikirere cya H2, SiC igashyirwa ku gice cya grafiti. Uburyo bwo gukora ibintu bifite isuku nyinshi; icyakora, ni amasahani yoroshye gusa ashobora gukorwa. Uburyo bwo gukora ibintu buhenze cyane kubera igihe cyo gukora ibintu buhoro buhoro.
Karubide ya Silikoni ikoze mu mwuka w’ubushyuhe (CVCSiC). Iyi nzira itangirana n’umusemburo wa girafu ukozwe mu buryo bwa girafu ukozwe mu buryo bwa hafi mu buryo bwa girafu. Uburyo bwo guhindura igice cya girafu butuma igice cya girafu kigira imiterere ya solid-state kugira ngo habeho SiC ya polycrystalline, stoichiometrically. Iyi nzira igenzurwa neza ituma imiterere igoye ikorwa mu gice cya SiC cyahinduwe burundu gifite ubushobozi bwo kwihanganira ibintu bikomeye kandi gifite ubuziranenge bwinshi. Uburyo bwo guhindura bugabanya igihe gisanzwe cyo gukora kandi bukagabanya ikiguzi ugereranyije n’ubundi buryo.* Inkomoko (usibye aho byavuzwe): Ceradyne Inc., Costa Mesa, Calif.
