Cubic Silicon Carbide (β-SiC)
Cubic Silicon Carbide (β-SiC)
Cubic silicon carbide ceramic powder ndi ufa wobiriwira wobiriwira. Mapangidwe ake a mamolekyulu ndi: SiC, kulemera kwa maselo 40.10, kachulukidwe 3.2g/cm3, malo osungunuka 2973 ℃, coefficient yowonjezera matenthedwe 2.98 × 10-6K- 1.
Silicon carbide ceramic powder ili ndi chiyero chapamwamba, kugawa tinthu tating'onoting'ono, ma pores ang'onoang'ono, ntchito ya sintering, mawonekedwe a kristalo nthawi zonse, matenthedwe abwino kwambiri, ndipo ndi semiconductor yomwe imatha kukana makutidwe ndi okosijeni pa kutentha kwakukulu; Ndevu za β-SiC ndi zazitali Chiŵerengero chachikulu cha m'mimba mwake, kutalika kwa pamwamba, chiŵerengero cha m'mimba mwake, ndi tinthu tating'onoting'ono mu ndevu, machitidwe ake ndi abwino kuposa ena kaya amizidwa m'malo owononga, mafakitale ndi migodi yowopsya kwambiri, kapena amatenthedwa kupitirira 1400 ° C. Zopangira malonda za ceramic kapena zitsulo, kuphatikiza ma aloyi a kutentha kwambiri.

Ntchito zazikulu za silicon carbide: Xinli Abrasive ikhoza kupereka silicon carbide kuti igwiritsidwe ntchito zosiyanasiyana, kuphatikizapo hexagonal kapena rhombohedral α-SiC ndi cubic β-SiC ndi β-SiC ndevu. Zipangizo zopangidwa ndi silicon carbide ndi mapulasitiki, zitsulo, ndi zoumba zimatha kusintha kwambiri zinthu zake zosiyanasiyana. Chifukwa cha kukhazikika kwake kwa kutentha kwambiri, mphamvu zambiri, komanso kutentha kwapamwamba, amagwiritsidwa ntchito kwambiri mu zipangizo zamagetsi za atomiki, zipangizo zamakina, kutentha kwapamwamba, ndi zipangizo zamagetsi ndi zamagetsi. , gawo la semiconductor, zida zotenthetsera zamagetsi ndi zopinga, etc. Itha kugwiritsidwanso ntchito muzotayira, zida za abrasive, zida zapamwamba zokanira, ndi zoumba zabwino.
cubic silicon carbide imapereka ntchito zosiyanasiyana m'mafakitale angapo, makamaka zamagetsi zamagetsi, zida za RF, zamagetsi zamagetsi, magawo a semiconductor, malo otentha kwambiri, masensa, ndi ma optoelectronics.
