Green silicon carbide le black silicon carbide: Phapang e tebileng ho feta mebala
Lefapheng le leholo la lisebelisoa tsa indasteri,silicon carbide e talalesilicon e ntšo carbide hangata li boleloa hammoho. Ka bobeli ke li-abrasives tsa bohlokoa tse entsoeng ke ho qhibiliha ha mocheso o phahameng ka har'a libopi tsa ho hanyetsa tse nang le lisebelisoa tse tala tse kang lehlabathe la quartz le petroleum coke, empa liphapang tsa tsona li feta hōle phapang ea mebala e holim'a metsi. Ho tloha ho liphapang tse poteletseng tsa thepa e tala, ho ea ho ho se tšoane ha litšobotsi tsa ts'ebetso, ho ea ho phapano e kholo ea maemo a ts'ebeliso, liphapang tsena ka kopanelo li thehile likarolo tse ikhethang tsa tse peli lefapheng la indasteri.
1 Phapang ea bohloeki ba thepa e tala le sebopeho sa kristale e khetholla litšobotsi tse fapaneng tsa tse peli.
Silicone carbide e talae entsoe ka petroleum coke le lehlabathe la quartz e le thepa e ka sehloohong, 'me letsoai le kenngoa bakeng sa ho hloekisoa. Ka ts'ebetso ena, lintho tse sa hloekang li fokotsehile ho isa tekanyong e kholo ka ho fetisisa, 'me kristale ke tsamaiso e tloaelehileng ea hexagonal e nang le likarolo tse bohale le likhutlo. Ts'ebetso ea thepa e tala ea silicon carbide e ntšo e bonolo, 'me ha ho na letsoai le eketsoang. Litšila tse kang tšepe le silicon tse setseng ka har'a thepa e tala li etsa hore likaroloana tsa eona tsa kristale li se ke tsa tloaeleha ka sebopeho le ho pota-pota le ho ba lerootho metseng le likhutlong.
2 Phapang ea thepa e tala le meaho e lebisa mekhoeng e fapaneng ea 'mele ea bobeli.
Mabapi le boima, boima ba Mohs basilicon carbide e talae ka ba 9.5, ea bobeli ho daemane, 'me e khona ho sebetsana le lisebelisoa tse thata haholo; silicon carbide e ntšo e ka ba 9.0, e nang le boima bo tlase hanyane. Mabapi le boima ba 'mele, silicon carbide e tala ke 3.20-3.25g / cm³, e nang le mohaho o teteaneng; silicon carbide e ntšo ke 3.10-3.15g/cm³, e batlang e hlephile. Mabapi le ts'ebetso, silicon carbide e tala e na le bohloeki bo phahameng, conductivity e ntle ea mocheso, motlakase oa motlakase le ho hanyetsa mocheso o phahameng, empa e brittle ebile e bonolo ho phunyeletsa metseng e mecha; silicon carbide e ntšo e na le conductivity e fokolang ea mocheso le motlakase oa motlakase, ho fokola ho fokolang, le ho hanyetsa matla a likaroloana.
3 Liphapang tsa tšebetso li laola sepheo sa ts'ebeliso ea tse peli.
Green silicon carbide e na leboima bo phahamengle likaroloana tse bohale, 'me e ntle ho sebetsana le lisebelisoa tse thata tse phahameng le tse tlaase: tšimong e seng ea tšepe, e ka sebelisoa bakeng sa ho sila ka khalase, ho itšeha ka ceramic, liphaphatha tsa silicon tsa semiconductor, le polishing ea safire; ts'ebetsong ea tšepe, e na le ts'ebetso e ntle haholo ea ho sebetsa ka mokhoa o nepahetseng bakeng sa lisebelisoa tse kang carbide e entsoeng ka samente le tšepe e thata, 'me e sebelisoa haholo lihlahisoa tse kang mabili a sila le li-discs tsa ho itšeha. Silicon carbide e ntšo haholo-holo e sebetsa ka thata-thata, lisebelisoa tse thata haholo 'me e loketse ho sebetsa ha litšepe tse se nang ferrous le lisebelisoa tse refractory tse kang tšepe e entsoeng ka tšepe, koporo le aluminium. Liketsahalong tse thata tse kang ho senya li-castings le ho tlosoa ha mafome a tšepe, e fetohile khetho e tloaelehileng indastering ka lebaka la litšenyehelo tse phahameng tsa eona.
Le hoja silicon e tala carbide lesilicon e ntšo carbideke karolo ea silicon carbide system, thepa ea bona ea 'mele le ea lik'hemik'hale le litšobotsi tsa ts'ebeliso li fapane haholo. Ka nts'etsopele e tsoelang pele ea mahlale a mahlale le thekenoloji ea ts'ebetso, silicon carbide e tala le silicon carbide e ntšo li lebelletsoe ho fihlela katoloso e pharalletseng ea ts'ebeliso libakeng tsa theknoloji e phahameng joalo ka tlhahiso ea semiconductor, ho sila ka nepo le matla a macha, ho fana ka tšehetso ea bohlokoa ea lisebelisoa bakeng sa nts'etsopele ea boleng bo holimo ea indasteri ea sejoale-joale.
