Carbide ya Silicon yitwara nka diyama. Ntabwo ari urumuri rworoshye gusa, ahubwo nibikoresho bikomeye bya ceramic kandi bifite ubushyuhe bwiza bwumuriro, kwaguka kwinshi kwumuriro kandi birwanya cyane acide na lyes.
Hamwe na silicon carbide ceramics ibintu bifatika biguma bihoraho kugeza ubushyuhe buri hejuru ya 1,400 ° C. Modulus yo hejuru ya Young> 400 GPa itanga umutekano muke. Ibikoresho bifatika bituma silicon karbide yateganijwe gukoreshwa nkibikoresho byubwubatsi. Silicon karbide ikora ruswa, abrasion hamwe nisuri nkubuhanga nkuko bihagaze kwambara. Ibigize bikoreshwa mubihingwa byimiti, urusyo, kwagura no gusohora cyangwa nka nozzles, kurugero.
"Impinduka za SSiC (carbide ya silicon yacuzwe) na SiSiC (silicon yinjiye muri silicon carbide) zishyizeho ubwazo. Iyanyuma irakwiriye cyane cyane kubyara ibice binini binini."
Carbide ya silicon ifite uburozi kandi irashobora gukoreshwa mubiribwa. Ubundi buryo busanzwe bukoreshwa mubikoresho bya silicon karbide ni tekinoroji yo gufunga ikoresheje amashanyarazi hamwe na kashe ya mashini, urugero muri pompe na sisitemu yo gutwara. Ugereranije nicyuma, karibide ya silicon itanga ibisubizo byubukungu cyane hamwe nigihe kirekire cyibikoresho iyo bikoreshejwe nibitangazamakuru bikaze, ubushyuhe bwinshi. Silicon carbide ceramics nayo nibyiza gukoreshwa mubihe bisabwa muri ballistique, umusaruro wimiti, ikoranabuhanga ryingufu, gukora impapuro kandi nkibigize sisitemu.
Imyitwarire ya silicon karbide, izwi kandi nka siliconized silicon carbide cyangwa SiSiC, ni ubwoko bwa karbide ya silicon ikorwa nigikorwa cyimiti hagati ya karubone cyangwa grafite hamwe na silikoni yashonze. Bitewe n'ibumoso hejuru ya silikoni, reaction ya silicon karbide ikunze kwitwa karubide ya siliconize, cyangwa amagambo ahinnye ya SiSiC.
Niba karibide nziza ya silicon ikorwa no gucumura ifu ya karubide ya silicon, mubusanzwe iba irimo ibimenyetso byimiti bita sintering aids, byongeweho kugirango bishyigikire inzira yo gucumura byemerera ubushyuhe buke bwo gucumura. Ubu bwoko bwa karibide ya silicon bakunze kwita karbide ya silicon yacumuye, cyangwa mu magambo ahinnye ya SSiC.
Ifu ya silicon karbide yunguka muri karubide ya silicon yakozwe nkuko byasobanuwe mu ngingo ya karubide ya silicon.
