Cas 409-21-2 silicon carbide ntụ ntụ dị ọcha nano SiC nanopowder na nanoparticles.

Silicon carbide (SiC), makwaara dị ka carborundum, bụ ngwakọta nke silicon na carbon nwere usoro kemịkal SiC. Ọ na-eme n'okike dị ka moissanite mineral dị oke ụkọ. A na-emepụta ntụ ntụ silicon carbide sịntetik kemgbe 1893 maka iji dị ka ihe na-ekpo ọkụ. Enwere ike jikọta ọka nke silicon carbide ọnụ site na ijikọ ka ọ mepụta ceramik siri ike nke a na-ejikarị na ngwa chọrọ ntachi obi dị elu, dị ka breeki ụgbọ ala, njigide ụgbọ ala na efere seramiiki n'ime akwa mkpuchi mgbo. Ngwa eletrọnịkị nke silicon carbide dị ka ọkụ-emitting diodes (LEDs) na ndị na-achọpụta na redio mmalite ka e gosipụtara na mbụ gburugburu 1907. A na-eji SiC na ngwaọrụ eletrọnkị semiconductor nke na-arụ ọrụ na oke okpomọkụ ma ọ bụ nnukwu voltaji, ma ọ bụ abụọ. Enwere ike itolite nnukwu kristal silicon carbide site na usoro Lely; Enwere ike ịkpụ ha n'ime ọla ndị a maara dị ka moissanite sịntetị. Enwere ike imepụta silicon carbide nwere ebe dị elu site na SiO2 dị n'ime ihe ọkụkụ.
