Ntụ ntụ silicon carbide akwụkwọ ndụ akwụkwọ ndụ na micropowder silicon carbide

Silicon carbide (SiC), nke a makwaara dị ka carborundum, bụ semiconductor nwere silicon na carbon nwere usoro kemịkalụ SiC. Ọ na-apụta n'okike dị ka moissanite mineral dị oke ụkọ. A na-emepụta ntụ ọka silicon carbide nke e ji ígwè rụọ kemgbe 1893 maka iji ya mee ihe dị ka ihe na-eme ka ihe ghara ịdị ọcha. Enwere ike ijikọ mkpụrụ nke silicon carbide ọnụ site na sintering iji mepụta seramiiki siri ike nke a na-ejikarị eme ihe n'ọtụtụ ebe na-achọ ntachi obi dị elu, dị ka brek ụgbọ ala, njide ụgbọ ala na efere seramiiki na uwe mkpuchi na-enweghị mgbọ. E gosipụtara ngwa eletrọniki nke silicon carbide dị ka diode na-enye ìhè (LEDs) na ihe nchọpụta na redio mbụ na 1907. A na-eji SiC na ngwaọrụ eletrọniki semiconductor nke na-arụ ọrụ na okpomọkụ dị elu ma ọ bụ voltaji dị elu, ma ọ bụ ha abụọ. Enwere ike ịkụ nnukwu kristal silicon carbide site na usoro Lely; enwere ike ịkpụ ha ka ọ bụrụ nkume dị oké ọnụ ahịa a maara dị ka moissanite sịntetik. Enwere ike ịmepụta silicon carbide nwere oke elu site na SiO2 dị na ihe ọkụkụ.

Shandong Zhongpeng Special Ceramics Co., Ltd bụ otu n'ime ihe ngwọta ọhụrụ seramiiki silicon carbide kachasị ukwuu na China. Seramiiki teknụzụ SiC: Ike Moh bụ 9 (ike Moh ọhụrụ bụ 13), yana ezigbo iguzogide mbuze na nchara, ezigbo nbibi - iguzogide na mgbochi oxidation. Ndụ ọrụ nke ngwaahịa SiC dị okpukpu 4 ruo 5 karịa ihe alumina 92%. MOR nke RBSiC bụ ugboro 5 ruo 7 nke SNBSC, enwere ike iji ya maka ụdị ndị ka mgbagwoju anya.
