Silicon Carbide e ji aka mee (RXSIC, ReSIC, RSIC, R-SIC). Ihe e ji aka mee bụ silicon carbide. A naghị eji ihe enyemaka njupụta eme ihe. A na-ekpo ọkụ kọmpat akwụkwọ ndụ akwụkwọ ndụ ruo ihe karịrị 2200ºC maka njikọta ikpeazụ. Ihe e ji aka mee nwere ihe dị ka 25% porosity, nke na-ebelata ihe onwunwe ya; agbanyeghị, ihe e ji aka mee nwere ike ịdị ọcha nke ukwuu. Usoro a dị oke ọnụ.
Mmeghachi omume nke Silicon Carbide (RBSIC). Ihe ndị e ji emepụta ihe ndị na-amalite bụ silicon carbide tinyere carbon. A na-etinye silicon gbazere agbaze n'ime ihe ndị dị ndụ n'ime ihe ndị a na-eme n'elu 1450ºC site na mmeghachi omume ahụ: SiC + C + Si -> SiC. Ọdịdị microstructure ahụ na-enwekarị oke silicon gabigara ókè, nke na-egbochi ihe onwunwe ya dị elu na iguzogide nchara. Mgbanwe dị nta na-eme n'oge usoro ahụ; agbanyeghị, a na-enwekarị oyi akwa silicon n'elu akụkụ ikpeazụ. A na-eji teknụzụ dị elu nke ZPC RBSiC eme ihe, na-emepụta mkpuchi mgbochi iyi, efere, taịlị, mkpuchi cyclone, blọk, akụkụ ndị na-adịghị mma, na ihe mkpuchi FGD na-eguzogide iyi na nchara, ihe mgbanwe okpomọkụ, ọkpọkọ, tubes, na ihe ndị ọzọ.
Nitride Bonded Silicon Carbide (NBSIC, NSIC). Ihe ndị e ji emepụta ihe bụ silicon carbide tinyere ntụ silicon. A na-agba kọmpat akwụkwọ ndụ akwụkwọ ndụ n'ime ikuku nitrogen ebe mmeghachi omume SiC + 3Si + 2N2 -> SiC + Si3N4 na-eme. Ihe ikpeazụ anaghị egosi mgbanwe nha n'oge nhazi. Ihe ahụ na-egosipụta obere ọkwa nke porosity (ihe dị ka 20%).
Direct Sintered Silicon Carbide (SSIC). Silicon carbide bụ ihe mmalite ihe eji arụ ọrụ. Ihe enyemaka njupụta bụ boron na carbon, njupụta na-emekwa site na usoro mmeghachi omume siri ike karịa 2200ºC. Njirimara okpomọkụ dị elu na nguzogide nchara dị elu n'ihi enweghị usoro nke abụọ dị ka iko na ókèala ọka.
Mmiri Mmiri Sintered Silicon Carbide (LSSIC). Silicon carbide bụ ihe mmalite ihe eji arụ ọrụ. Ihe na-enyere aka na njupụta bụ yttrium oxide tinyere aluminum oxide. Njupụta na-apụta n'elu 2100ºC site na mmeghachi omume mmiri mmiri ma na-ebute usoro nke abụọ dị ka iko. Njirimara igwe na-adịkarị mma karịa SSIC, mana njirimara okpomọkụ dị elu na nguzogide nchara adịghị mma.
A na-eji ntụ silicon carbide dị ọkụ eme ihe (HPSIC). A na-eji ntụ silicon carbide eme ihe dị ka ihe mmalite. Ihe enyemaka njupụta na-abụkarị boron tinyere carbon ma ọ bụ yttrium oxide tinyere aluminum oxide. Njupụta na-eme site na itinye nrụgide mekaniki na okpomọkụ n'ime oghere graphite n'otu oge. Ọdịdị ha bụ efere dị mfe. Enwere ike iji obere ihe enyemaka njupụta. A na-eji ihe onwunwe mekaniki nke ihe ndị a na-agbanye ọkụ eme ihe dị ka ntọala nke a na-atụnyere usoro ndị ọzọ. Enwere ike ịgbanwe ihe onwunwe eletrik site na mgbanwe na ihe enyemaka njupụta.
CVD Silicon Carbide (CVDSIC). A na-emepụta ihe a site na usoro nchekwa anwụrụ ọkụ (CVD) nke gụnyere mmeghachi omume: CH3SiCl3 -> SiC + 3HCl. A na-eme mmeghachi omume ahụ n'okpuru ikuku H2 ebe a na-etinye SiC na ihe ndọba graphite. Usoro a na-eweta ihe dị ọcha nke ukwuu; agbanyeghị, naanị efere dị mfe ka enwere ike ime. Usoro a dị oke ọnụ n'ihi oge mmeghachi omume dị nwayọ.
Agụụ Kemịkalụ Agụụ Silicon Carbide (CVCSiC). Usoro a na-amalite site na ihe eji emepụta graphite nke e ji aka rụọ nke e ji mee ka ọ dị ka ihe dị nso na net na steeti graphite. Usoro ntụgharị ahụ na-etinye akụkụ graphite ahụ na mmeghachi omume siri ike nke in situ vapor iji mepụta SiC polycrystalline, nke a na-achịkwa nke ọma. Usoro a nke a na-achịkwa nke ọma na-enye ohere ka e mepụta atụmatụ dị mgbagwoju anya na akụkụ SiC a gbanwere kpamkpam nke nwere njirimara nnabata siri ike na ịdị ọcha dị elu. Usoro ntụgharị ahụ na-ebelata oge mmepụta nkịtị ma na-ebelata ọnụ ahịa karịa ụzọ ndị ọzọ.* Isi mmalite (ma e wezụga ebe a kpọtụrụ aha): Ceradyne Inc., Costa Mesa, Calif.
