Nzira yekugadzira silicon carbide inoshandiswa muindasitiri ndeyekubvisa jecha re quartz remhando yepamusoro ne calcined petroleum coke muchoto chemagetsi chinodziya. Mabhuroko e silicon carbide akacheneswa anogadzirwa kuita zvinhu zvine saizi dzakasiyana-siyana dzekugoverwa kwezvikamu nekupwanya, kushambidza zvine acid yakasimba uye alkali, michina yekuparadzanisa magnetic uye kuparadzanisa kana kuparadzanisa mvura.
Silicon carbide ine mhando mbiri dzakajairika dze black silicon carbide ne green silicon carbide, dzose dziri dze α-SiC. ① Black silicon carbide ine inenge 95% SiC, uye ductility yayo yakakwira kupfuura green silicon carbide, iyo yakawanda inoshandiswa kugadzira nekugadzirisa zvinhu zvisina simba rakawanda rekudhonza, zvakaita segirazi rakaiswa laminated, porcelain, dombo, refractory, simbi yenguruve nesimbi dzinokosha. ② Green silicon carbide ine SiC inenge 97% pamusoro, kuzvirodza kwakanaka, mazhinji acho anoshandiswa kugadzira nekugadzirisa maturusi e carbide, titanium metal uye optical lenses, uye anoshandiswawo pakunatsa cylinder liner nekupukuta maturusi esimbi anomhanyisa. Pamusoro pezvo, kune cubic metres yesilicon carbide, inova kristaro yegirini yakareruka yakagadzirwa nemaitiro matsva, uye inoshandiswa kugadzira mold yakakodzera kugadzika kwepamusoro, iyo inogona kuita kuti roughness yekumusoro kubva kuRa32 ~ 0.16μm igadziriswe kusvika kuRa0.04 ~ 0.02μm.
Mashandisirwo makuru e silicon carbide inonyungudutsa reaction sintering
(1) Sechinhu chisingapfeki, chinogona kushandiswa sechiumbwa, senge jecha vhiri, whetstone, grinding vhiri, jecha tile, nezvimwewo.
(2) Semushonga wekubvisa oxidizing uye zvinhu zvinodzivirira ngura muindasitiri yesimbi. Silicon carbide inonyanya kusanganisira mashandisirwo mana makuru, anoti: ceramics dzinoshanda, zvinhu zvinoramba kushanda zvakanaka, zvinhu zvinodzivirira kupera simba uye zvinhu zvinonyungudutsa. Padanho rino, silicon carbide roughage inogona kupihwa nenzira dzakawanda, iyo isiri chigadzirwa chetekinoroji yepamusoro, uye kushandiswa kwe nano-silicon carbide powder ine huwandu hwakawanda hwesainzi netekinoroji hazvigone kuunza mhedzisiro yakakura munguva pfupi.
(3) kristaro imwe chete yakachena kwazvo, yakakodzera kugadzirwa kwezvinhu zve semiconductor, kugadzirwa kwefibers dzemakemikari dzesilicon carbide.
Mashandisirwo: Kune masero e photovoltaic ane 3-12 feet, masero e photovoltaic, potassium arsenide, quartz resonators nezvimwe zvinocheka mitsetse. Indasitiri ye solar photovoltaic, indasitiri ye semiconductor, piezoelectric crystal industry chain engineering project raw material processing.
Reactive sintering silicon carbide - zvikonzero zvekuumbwa kwayo
Mwero wekumanikidzwa kwakanyanya uye tembiricha yepamusoro unogadzirwa mukati menyika unopfapfaidzwa kubva muvhu nelava. Sezvakaita Thailand, Australia, Shandong yeChina, United States nedzimwe nyika. Jade yesimbi inogadzirwa ne touch metamorphism. Sezvakaita Myanmar, Kashmir, Anhui yeChina nedzimwe nzvimbo. Rubies pasi rose dzinonyanya kubva mu placers. Izvi zvinobva kuburikidza nemhando dzakasiyana dze ergonomic ecosystem, blue gems by erosion aggregation reaction sintering silicon carbide ne pure natural silicon ore, carbon, wood slag, industrial salt sezvinhu zvakagadzirwa, mu electric heating furnace heating heating reflection. Kuwedzera wood slag ndeyekugadzira chidimbu chidiki chezvinhu zvakasanganiswa pakupisa kwakanyanya kugadzira chimiro chine maburi, icho chinobatsira kuratidza vapor body yakakura uye volatility yekubvisa, kudzivirira tsaona dzekuputika, nekuda kwekugadzirwa kwe 1 ton yesilicon carbide, inogona kugadzira inenge 1.4t ye carbon monoxide (CO). Basa re industrial salt (NaCl) rinobatsira kubvisa aluminium oxide, compounds nezvimwe zvasara muzvinhu.
