Silicon carbide brick
Silicon carbide brick
1. Isi ihe dị na blọgụ carbide silicon bụ SiC, ọdịnaya bụ 72%-99%. A na -eji brik carbide silicon arụ ọrụ dị iche iche na akụrụngwa ọkụ n’ihi ngwakọta dị iche iche. Dabere na usoro njikọkọ dị iche iche, a na -ekewa ndị na -emepụta brik silicon carbide na njikọ ụrọ, njikọta Sialon, njikọ alumina, njikọ onwe, njikọta aluminom dị elu, njikọta silicon nitride, na ndị ọzọ. Kedu ihe eji brik carbide silicon mee? Kedu ngwa ndị bụ isi?
2. N’ihi na akụrụngwa nke biliki carbide silicon bụ carbide silicon, carbide silicon, nke a makwaara dị ka emery, na-eme site n’ọkụ na-agbaze ngwa ngwa dị ka aja quartz, coke, na ibe osisi. A na -ejikarị carbide silicon eme ihe nrụpụta dị elu n’ihi akụrụngwa kemịkalụ ya kwụsiri ike, conductivity thermal dị elu, ọnụọgụ mgbasawanye ọkụ dị ala, yana nguzogide dị mma.
3. A na-ahazi brik carbide silicon n’ime akwa ọkụ na-enwu enwu site na iji njirimara nke carbide silicon dị ka nguzogide corrosion, nguzogide okpomọkụ dị elu, ike dị elu, conductivity thermal dị mma, na nguzogide mmetụta, a na-ejikwa ya n’ọtụtụ okpomọkụ dị elu. akụrụngwa ọkụ.
4. Ngwaahịa carbide silicon na -eji carbide silicon dị ka akụrụngwa, gbakwunye ụrọ, silicon oxide na ihe ndị ọzọ na -ejikọ ọnụ na 1350 ruo 1400 ° C. Silicon carbide na silicon ntụ ntụ nwekwara ike bụrụ ngwaahịa silicon nitride-silicon carbide na ikuku nitrogen n’ime ọkụ eletrik. Ngwaahịa carbon nwere ọnụọgụ mmụba dị ọkụ dị ala, conductivity thermal dị elu, nguzogide ujo dị ọkụ, yana ike okpomọkụ dị elu. Ọ naghị adị nro mgbe ejiri ogologo oge mee ya na oke okpomọkụ, acid na alkali ọ bụla adịghị emebi ya, nwere ezigbo nguzogide nnu, ọla na slag adịghị ede ya. Ọ dị nfe ma bụrụkwa ihe na-eguzogide oke okpomọkụ dị elu. Mwepu ya bụ na ọ dị mfe oxidize na oke okpomọkụ yana ọ dịghị mma maka ojiji na ikuku ikuku. A na-eji ngwaahịa carbon eme ihe na akwa mkpuchi ọkụ dị elu (ala ọkụ, ọkụ, akụkụ ala nke oghere ọkụ, wdg), yana mkpuchi nke nnukwu ite ọkụ na-agbaze.
