Mokhoa oa tlhahiso ea indasteri oa carbide ea silicon e sintered reaction-sintered ke ho ntša lehlabathe la quartz la boleng bo holimo le coke ea petroleum e nang le calcium ka ontong ea motlakase e futhumatsang. Liboloko tsa carbide ea silicon e hloekisitsoeng li etsoa thepa e nang le kabo e fapaneng ea boholo ba likaroloana ka ho sila, ho hlatsoa ka asiti e matla le alkali, lisebelisoa tsa karohano ea makenete le ho hlakola kapa ho arola metsi.
Carbide ea silicon e na le mefuta e 'meli e tloaelehileng ea motheo ea carbide ea silicon e ntšo le carbide ea silicon e tala, tseo kaofela e leng tsa α-SiC. ① Carbide ea silicon e ntšo e na le hoo e ka bang 95% ea SiC, 'me ho teteana ha eona ho phahame ho feta carbide ea silicon e tala, eo boholo ba eona e sebelisetsoang ho hlahisa le ho sebetsana le thepa e tala e nang le matla a tlase a ho tensile, joalo ka khalase e laminated, porcelain, lejoe, refractory, tšepe ea kolobe le litšepe tsa bohlokoa. ② Carbide ea silicon e tala e na le SiC hoo e ka bang 97% ho feta, ho itlhokomela ho molemo, boholo ba tsona li sebelisetsoa tlhahiso le ts'ebetso ea lisebelisoa tsa carbide, tšepe ea titanium le lilense tsa optical, 'me li boetse li sebelisetsoa ho holisa liner ea silinda le ho bentša lisebelisoa tsa tšepe tse lebelo le phahameng. Ho phaella moo, ho na le li-cubic metres tsa silicon carbide, e leng kristale e tala e bobebe e entsoeng ke ts'ebetso e ncha, 'me e sebelisetsoa ho hlahisa hlobo e loketseng ho jara ho qeta ho hoholo, e ka etsang hore bokaholimo bo be thata ho tloha ho Ra32 ~ 0.16μm e be ts'ebetso ho ea ho Ra0.04 ~ 0.02μm.
Tšebeliso e ka sehloohong ea silicon carbide e sintering ea karabelo
(1) Jwalo ka thepa e sa tsofaleng, e ka sebediswa e le hlobo, jwalo ka lebili la lehlabathe, lejwe la lejwe, lebili la ho sila, thaele ya lehlabathe, jj.
(2) Jwalo ka moemedi wa ho tlosa okside le thepa e hanelang mafome bakeng sa indasteri ya tshepe. Silicon carbide e kenyeletsa haholo-holo tshebediso e mene e meholo, e leng: diseramike tse sebetsang, thepa e phahameng e hanyetsang, thepa e hanelang ho tsofala le thepa e tala ya ho qhibilihisa. Mothating ona, roughage ya silicon carbide e ka fanwa ka ditsela tse ngata, e leng se seng sehlahisoa sa theknoloji e hodimo, mme tshebediso ya phofo ya nano-silicon carbide e nang le dikahare tse hodimo haholo tsa saense le theknoloji ho ka etsahala hore e se hlahise ditlamorao tsa sekala ka nako e kgutshwane.
(3) kristale e le 'ngoe e hloekileng haholo, e loketseng tlhahiso ea thepa ea semiconductor, tlhahiso ea likhoele tsa lik'hemik'hale tsa silicon carbide.
Bongata ba ts'ebeliso: Bakeng sa lisele tsa photovoltaic tsa limithara tse 3-12, lisele tsa photovoltaic, potassium arsenide, li-resonator tsa quartz le tse ling tse sehiloeng ka mela. Indasteri ea photovoltaic ea letsatsi, indasteri ea semiconductor, projeke ea boenjiniere ba ketane ea indasteri ea kristale ea piezoelectric ts'ebetso ea thepa e tala.
Carbide ea silicon e sintering e sebetsang - mabaka a ho thehoa
Tekanyetso e phahameng haholo ea khatello le mocheso o phahameng e hlahisoang botebong ba lefats'e e fafatsoa mobung ka seretse se chesang. Joalo ka Thailand, Australia, Shandong ea Chaena, United States le linaha tse ling. Jade ea tšepe e hlahisoa ka ho ama metamorphism. Joalo ka Myanmar, Kashmir, Anhui ea Chaena le libaka tse ling. Lirubi lefatšeng li fumanoa haholo-holo ho tsoa ho li-placers. Ke ka mefuta e fapaneng ea liemeralde tsa tlhaho tsa tlhaho, mahakoe a maputsoa ka khoholeho ea mobu, karabelo ea ho kopanya silicon carbide ka oli ea tlhaho ea silicon e hloekileng, carbon, slag ea lehong, letsoai la indasteri e le thepa e tala e hlahisoang, ka har'a motlakase o futhumatsang sebōpi o bonahatsang tlhahiso. Ho eketsoa ha slag ea lehong ke ho etsa sengoathoana se senyenyane sa thepa e tsoakiloeng mochesong o phahameng ho hlahisa sebopeho se nang le masoba, se loketseng ho bonahatsa 'mele o moholo oa mouoane le ho feto-fetoha ha maemo ao ho ka tlosoang ho' ona, ho thibela likotsi tsa ho phatloha, ka lebaka la tlhahiso ea tonne e le 'ngoe ea silicon carbide, e ka hlahisa hoo e ka bang 1.4t ea carbon monoxide (CO). Karolo ea letsoai la indasteri (NaCl) e loketse ho tlosa aluminium oxide, metsoako le masala a mang thepa.
