Cubic Silicon Carbide (β-SiC)
Cubic silicon carbide ceramic ntụ ntụ bụ ntụ ntụ-acha akwụkwọ ndụ akwụkwọ ndụ. Usoro ihe omimi ya bụ: SiC, ịdị arọ molecular 40.10, njupụta 3.2g/cm3, ebe agbaze 2973 ℃, ọnụọgụ mgbasawanye thermal 2.98 × 10-6K- 1.
Silicon carbide seramiiki ntụ ntụ nwere ịdị ọcha dị elu, nkesa nha nha dị warara, obere pores, ọrụ sintering dị elu, usoro kristal mgbe niile, ezigbo ikuku thermal, yana semiconductor nke nwere ike iguzogide oxidation na oke okpomọkụ; β-SiC whiskers bụ ogologo nnukwu dayameta ruru, elu elu imecha, elu dayameta ruru, na obere urughuru ọdịnaya na whiskers, ya arụmọrụ dị mma karịa ndị ọzọ ma ọ na-emikpu na a corrosive gburugburu ebe obibi, oké abrasive ulo oru na Ngwuputa, ma ọ bụ n'ikuku okpomọkụ karịrị 1400 ° C. Alloys seramiiki ma ọ bụ ígwè dị n'ahịa, gụnyere alloys okpomọkụ ultrahigh.
