Ukusetshenziswa Okukhulu Kwe-Silicon Carbide

I-silicon carbide emnyama yenziwe ngesihlabathi se-quartz kanye ne-petroleum coke silica njengezisetshenziswa zokusetshenziswa eziyinhloko ngokusebenzisa ukuncibilika okunezinga lokushisa eliphezulu esithandweni somlilo. Ukuqina kwayo kuphakathi kwe-corundum nedayimane, amandla ayo okusebenza aphakeme kune-corundum, futhi i-brittle futhi ibukhali. I-silicon carbide eluhlaza yenziwe nge-petroleum coke ne-silica njengezinto zokusetshenziswa eziyinhloko, nosawoti owengezwe njengesengezo, futhi inyibilika ekushiseni okuphezulu esithandweni somlilo. Ukuqina kwayo kuphakathi kwe-corundum nedayimane, futhi amandla ayo omshini aphakeme kune-corundum.

Ngakho yiziphi ukusetshenziswa okuyinhloko kwe-silicon carbide?
1. Ama-Abrasives - Ikakhulukazi ngenxa yokuthi i-silicon carbide inobulukhuni obuphezulu, ukuzinza kwamakhemikhali kanye nokuqina okuthile, i-silicon carbide ingasetshenziswa ukwenza ama-abrasives aboshwe, ama-abrasive agqinsiwe kanye nokugaya mahhala ukucubungula ingilazi nezitsha zobumba. , itshe, insimbi eyinsimbi nezinye izinsimbi ezingenayo insimbi, i-carbide, i-titanium alloy, amathuluzi okusika insimbi enesivinini esikhulu namasondo okugaya, njll.

2. Izinto ezikwazi ukumelana nokugqwala---Ikakhulukazi ngenxa yokuthi i-silicon carbide inezinga eliphezulu lokuncibilika (izinga lokubola), ukungabi namandla kwamakhemikhali nokumelana nokushaqeka okushisayo, i-silicon carbide ingasetshenziswa kuma-abrasives kanye neziko lomlilo lomlilo we-ceramic. Amapuleti e-Shed nama-sagger, izitini ze-silicon carbide zeziko lokuhluza isilinda mpo embonini yokuncibilikisa i-zinc, ama-aluminium electrolytic cell linings, ama-crucible, izinto ezincane zesithando somlilo neminye imikhiqizo ye-silicon carbide ceramic.

3. Ukusetshenziswa kwamakhemikhali-ngoba i-silicon carbide ingabola kunsimbi encibilikisiwe futhi isabelane nomoya-mpilo nama-oxide ensimbi ensimbi encibilikisiwe ukuze ikhiqize i-carbon monoxide ne-silicon-containing slag. Ngakho-ke, ingasetshenziswa njenge-ejenti yokuhlanza yokuncibilikisa insimbi, okungukuthi, njenge-deoxidizer kanye ne-cast iron structure improver ekwenzeni insimbi. Lokhu ngokuvamile kusebenzisa ubumsulwa obuphansi be-silicon carbide ukunciphisa izindleko. Ingasetshenziswa futhi njengento eluhlaza yokukhiqiza i-silicon tetrachloride.

4. Izicelo zikagesi - ezisetshenziswa njengezinto zokushisa, izakhi zokumelana ne-non-linear kanye nezinto eziphezulu ze-semiconductor. Izinto zokushisisa ezifana ne-silicon carbon rods (efanele iziko likagesi elihlukahlukene elisebenza ku-1100 kuya ku-1500°C), izakhi zokumelana ne-non-linear, namavalvu ahlukahlukene okuvikela umbani.
