Xargaha iyo duubayaasha carbide-ka ee silikoonka ah
Alwaaxyada iskutallaabta ah ee ZPC-RBSiC (SiSiC) waxay leeyihiin xoog sare mana jiraan wax isbeddel ah xitaa heerkulka aadka u sarreeya. Alwaaxyadu waxay muujiyaan cimri dheer oo hawlgal ah. Alwaaxyadu waa alaabta guriga ee ugu habboon ee loogu talagalay xirashada nadaafadda iyo isticmaalka foornada korontada. Shang mei RBSiC (SiSiC) waxay leedahay kuleyl aad u fiican, sidaa darteed waxaa la heli karaa si loo badbaadiyo tamarta iyadoo miisaan yar la saarayo gaariga foornada.
Alwaaxyada iyo duubayaasha carbide-ka ee silicon-ka ayaa loo isticmaalaa sidii qaab-dhismeedyo rarista ah oo lagu sameeyo foornooyinka soo saara, kuwaas oo beddeli kara saxanka silicon ee caadiga ah ee ku xidhan oksaydhka iyo tiirka mullite maadaama ay leeyihiin faa'iidooyin wanaagsan sida keydinta meelaha, shidaalka, tamarta iyo sidoo kale waqtiga dab-damiska oo gaaban, cimriga agabkanina waa dhowr jeer kuwa kale, waa alaab guri oo aad ugu habboon. Alwaaxyada carbide-ka ee silicon-ka waxaa inta badan loo isticmaalaa xubnaha qaadista culeyska ee foornada tunnel-ka, foornada shuttle-ka iyo foornada kanaalka laba-geesoodka ah. Waxa kale oo loo isticmaali karaa sida alaabta guriga ee foornada ee warshadaha dhoobada iyo kuwa iska caabbinta.
Alwaaxyo leh awood sare oo qaadis heerkul sare leh oo leh isticmaal ballaaran oo muddo dheer ah iyada oo aan la qaloocin, gaar ahaan ku habboon foornada tunnel-ka, foornada shuttle-ka, foornada laba-lakab leh iyo qaab-dhismeedka kale ee foornada warshadaha. Naadiyadu waxay khuseeyaan dhoobada la isticmaalo ee maalinlaha ah, dhoobada nadaafadda, dhoobada dhismaha, walxaha birlabta iyo aagga dab-shidka heerkulka sare leh ee foornada rogidda.

Shirkadda Shandong Zhongpeng Special Ceramics Co., Ltd waa mid ka mid ah xalalka ugu waaweyn ee walxaha cusub ee dhoobada ah ee silicon carbide ee Shiinaha. Dhoobada farsamada ee SiC: Adkaanshaha Moh waa 9 (adkeysiga New Moh waa 13), oo leh iska caabin aad u fiican oo ka dhan ah nabaad-guurka iyo daxalka, xoqid aad u fiican - iska caabin iyo ka-hortagga oksaydhka. Nolosha adeegga ee badeecada SiC waa 4 ilaa 5 jeer ka dheer 92% walxaha alumina. MOR ee RBSiC waa 5 ilaa 7 jeer ka badan SNBSC, waxaa loo isticmaali karaa qaabab badan oo adag. Habka xigashada waa mid degdeg ah, gaarsiintu waa sidii la ballanqaaday tayadana waa mid aan la barbar dhigi karin. Had iyo jeer waxaan ku adkaysannaa inaan ka hortagno yoolalkayaga oo aan qalbiyadeenna dib ugu celinno bulshada.
