N'oge a na-etinye ihe dị oke ọkụ, nhọrọ nke ihe dị oke mkpa. N'ime ha, ihe silicon carbide nke a na-etinye na mmeghachi omume aghọọla ihe a na-ahọrọ n'ihi arụmọrụ ya dị mma. Silicon carbide nke a na-etinye na mmeghachi omume bụ ihe seramiiki nke a na-emepụta site na mmeghachi omume nke ntụ ntụ carbon na silicon n'oge okpomọkụ dị elu.
Nke mbụ, silicon carbide nke a na-akpọ reaction-sinted nwere ezigbo nkwụsi ike okpomọkụ dị elu. Ọ nwere ike ịnọgide na-enwe ike mechanical na nkwụsi ike kemịkalụ ya na oke okpomọkụ ruru ogo 2,000 Celsius. Nke a na-eme ka ọ dị mma maka ojiji okpomọkụ dị elu, dịka n'ime ụlọ ọrụ mmepụta mmanụ, ígwè na seramiiki.
Nke abụọ, silicon carbide nke a na-akpọ reaction-sinted carbide nwere ezigbo iguzogide iyi. Ihe a nwere ezigbo iguzogide iyi ma nwee ike ịnọgide na-adịru ogologo oge n'ebe esemokwu na iyi siri ike. Ya mere, a na-ejikarị ya eme ihe n'ọhịa igwe e ji gweri ihe, bee ihe na ngwa e ji ehicha ihe.
Tinyere nke ahụ, silicon carbide nke a na-akpọ reaction-sinted nwekwara ezigbo thermal conductivity na kemikal inertia. Ọ nwere ike ime ka okpomọkụ dị ngwa ngwa ma na-egosi ezigbo mgbochi nchara na gburugburu ebe ruru unyi dịka acid na alkali. Nke a na-eme ka a na-ejikarị ya eme ihe n'ụlọ ọrụ kemịkalụ na njikwa okpomọkụ.
Ọ dị mkpa ịmara na usoro nkwadebe nke silicon carbide nke e ji mmeghachi omume mee dị mgbagwoju anya, nke chọrọ okpomọkụ dị elu na ọnọdụ mmeghachi omume pụrụ iche.

Na nchịkọta, dịka ihe dị oke okpomọkụ, silicon carbide nke a na-akpọ reaction-sinted carbide bụ nhọrọ zuru oke maka ọtụtụ ojiji okpomọkụ dị elu n'ihi nkwụsi ike okpomọkụ dị elu ya, iguzogide iyi, ike okpomọkụ na inertia kemịkalụ.
