Mokhoa oa tlhahiso ea indasteri oa reaction-sintered silicon carbide ke ho ntša lehlabathe la boleng bo holimo la quartz le calcined petroleum coke ka seboping sa mocheso oa motlakase. Li-block tsa silicon carbide tse hloekisitsoeng li entsoe lihlahisoa tse nang le likarolo tse fapaneng tsa boholo ba likaroloana ka ho senya, ho hlatsoa acid e matla le alkali, lisebelisoa tsa ho arohana ha makenete le ho hlahloba kapa ho arola metsi.
Silicon carbide e na le mefuta e 'meli e tloaelehileng ea motheo ea silicon carbide e ntšo le silicon carbide e tala, tseo kaofela e leng tsa α-SiC. ① Black silicon carbide e na le hoo e ka bang 95% SiC, 'me ductility ea eona e phahame ho feta silicon carbide e tala, eo boholo ba eona e sebelisetsoang ho hlahisa le ho sebetsana le lisebelisoa tse tala ka matla a tlaase, joalo ka khalase ea laminated, porcelain, lejoe, refractory, tšepe ea kolobe le tšepe tsa bohlokoa. ② Green silicon carbide e na le SiC hoo e ka bang 97% ka holimo, ho itšeha ho molemo, boholo ba tsona li sebelisetsoa ho hlahisa le ho lokisa lisebelisoa tsa carbide, tšepe ea titanium le lilense tsa optical, hape li sebelisetsoa ho holisa li-cylinder liner le ho bentša ka lebelo le phahameng. lisebelisoa tsa tšepe. Ho feta moo, ho na le li-cubic metres tsa silicon carbide, e leng kristale e tala e khanyang e entsoeng ke ts'ebetso e ncha, 'me e sebelisetsoa ho hlahisa hlobo e loketseng ho jara super-finishing, e ka etsang hore ho be thata ho tloha ho Ra32 ~ 0.16μm ho sebetsa. ho ea ho Ra0,04 ~ 0,02μm.
Ts'ebeliso ea mantlha ea reaction sintering silicon carbide
(1) E le thepa e sa sebetseng, e ka sebelisoa e le hlobo, joalo ka lebili la lehlabathe, whetstone, lebili la ho sila, tile ea lehlabathe, joalo-joalo.
(2) E le moemeli oa deoxidizing le lisebelisoa tse thibelang ho bola bakeng sa indasteri ea metallurgic. Silicon carbide haholo-holo e kenyelletsa litšebeliso tse 'ne tsa mantlha, e leng: lirafshoa tse sebetsang, lisebelisoa tsa boleng bo holimo tse hanang, thepa e sa senyeheng le lisebelisoa tse tala tse qhibilihang. Mothating ona, silicon carbide roughage e ka fanoa ka mekhoa e mengata, eo e seng sehlahisoa sa theknoloji e phahameng, 'me tšebeliso ea phofo ea nano-silicon carbide e nang le litaba tse phahameng haholo tsa saense le thekenoloji ho ke ke ha etsahala hore e hlahise liphello tse kholo ka nako e khutšoanyane.
(3) kristale e le 'ngoe e hloekileng haholo, e loketseng tlhahiso ea thepa ea semiconductor, tlhahiso ea silicon carbide chemical fibers.
Sebaka sa kopo: Bakeng sa lisele tsa photovoltaic tse 3-12, lisele tsa photovoltaic, potassium arsenide, li-quartz resonator le tse ling tsa ho khaola line. Indasteri ea letsatsi la photovoltaic, indasteri ea semiconductor, indasteri ea boenjiniere ba kristale ea piezoelectric projeke ea lisebelisoa tse tala.
Reactive sintering silicon carbide - mabaka a sebopeho
Khatello e phahameng haholo le maemo a mocheso a phahameng a hlahisoang khubung ea lefatše a fafatsoa ho tsoa fatše ka seretse se chesang. Tse kang Thailand, Australia, Shandong ea Chaena, United States le linaha tse ling. Steel jade e hlahisoa ke touch metamorphism. Joalo ka Myanmar, Kashmir, Anhui ea China le libaka tse ling. Lirubi lefatšeng ka bophara li tsoa ho li-placers. Ke ka mefuta e fapaneng ea liemerald tsa tlhaho tsa tlhaho, mahakoe a maputsoa ka khoholeho ea mobu ka ho kopanya silicon carbide e nang le oli e hloekileng ea silicon ea tlhaho, k'habone, slag ea patsi, letsoai la indasteri e le lisebelisoa tse tala tse hlahisoang ka har'a sebōpi sa motlakase se futhumatsang se bonts'ang moloko. Ho eketsoa ha lehong slag ke ho etsa sengoathoana se senyenyane sa thepa e tsoakiloeng mochesong o phahameng ho hlahisa sebopeho sa porous, se loketseng ho bonahatsa 'mele o moholo oa mouoane le ho hloka botsitso ho tloha ho oona, ho thibela likotsi tsa ho phatloha, ka lebaka la moloko. ea 1 tonne ea silicon carbide, e ka hlahisa hoo e ka bang 1.4t ea carbon monoxide (CO). Karolo ea letsoai la indasteri (NaCl) e thusa ho tlosa aluminium oxide, metsoako le masala a mang a thepa.
