Karubide ya silikoni ikora nka diyama. Ntabwo ari yo yoroheje gusa, ahubwo ni n'ibikoresho bikomeye bya ceramic kandi ifite ubushobozi bwo gutwara ubushyuhe bwinshi, ubushyuhe buke kandi irwanya aside na liye cyane.
Hamwe na silicon carbide ceramics, imiterere y'ibikoresho igumaho kugeza ku bushyuhe buri hejuru ya 1,400°C. Modulus ya Young iri hejuru ya 400 GPa ituma habaho ubudahangarwa bwiza mu ngero. Iyi miterere y'ibikoresho ituma silicon carbide yagenewe gukoreshwa nk'ibikoresho by'ubwubatsi. Silicon carbide irwanya ingese, kwangirika no gushwanyagurika mu buryo bugezweho nk'uko ihangana n'ubwangirike bw'imitsi. Ibice bigize ibikoresho bikoreshwa mu nganda zikora imiti, inganda, inganda zikora extruders cyangwa nk'imizingo, urugero.
“Izindi nyuguti za SSiC (silicon carbide) na SiSiC (silicon carbide infilted silicon) zarashyizweho ubwazo. Izi za nyuma zikwiriye cyane cyane mu gukora ibice bikomeye by’ingenzi.”
Karubide ya silikoni ifite uburozi kandi ishobora gukoreshwa mu nganda z'ibiribwa. Indi mikoreshereze isanzwe y'ibice bya silikoni ni ikoranabuhanga rikoresha uburyo bwo gufunga hakoreshejwe ibyuma bifunga ibintu (friction bearings) n'ibice by'ibyuma bifunga ibintu, urugero nko mu mashini zikoresha pompe na drive systems. Ugereranyije n'ibyuma, karubide ya silikoni itanga ibisubizo bihendutse cyane kandi biramba iyo ikoreshejwe mu bikoresho bishyushye kandi bishyushye cyane. Ibikoresho bya silikoni bya silikoni nabyo ni byiza gukoreshwa mu bihe bigoye mu gukora ballistics, mu gukora imiti, mu ikoranabuhanga ry'ingufu, mu gukora impapuro no mu bice by'imiyoboro.
Karubide ya silikoni ifatanye na Reaction, izwi kandi nka karubide ya silikoni cyangwa SiSiC, ni ubwoko bwa karubide ya silikoni ikorwa n'uburyo bwa shimi buhuza karuboni cyangwa grafiti ifite silicon ishongeshejwe. Bitewe n'ibisigazwa bya silikoni, karubide ya silikoni ifatanye na reaction ikunze kwitwa karubide ya silikoni ifatanye na silicon, cyangwa incamake yayo SiSiC.
Iyo karubide ya silikoni ikozwe binyuze mu gusya ifu ya silikoni, akenshi iba irimo ibisigazwa by'imiti yitwa sintering aids, byongerwamo kugira ngo bishyigikire inzira yo gusya binyuze mu kugabanya ubushyuhe bwo gusya. Ubwo bwoko bwa silikoni bukunze kwitwa sintered silicon carbide, cyangwa mu magambo ahinnye SSiC.
Ifu ya karubide ya silikoni iboneka muri karubide ya silikoni ikorwa nk'uko bivugwa mu ngingo ya karubide ya silikoni.
