Silicon carbide powder: Tšebeliso ea nako e tlang? 

High Purity Silicon Carbide Powder: Tataiso e FeletsengBofofu ba silicon carbide (SiC) bo hloekileng ke thepa ea bohlokoa lits'ebetsong tse fapaneng tse tsoetseng pele tsa theknoloji. Sengoliloeng sena se fana ka kakaretso e felletseng ea thepa ea eona, ts'ebeliso, mekhoa ea tlhahiso, le mekhoa ea 'maraka, e shebane le litlhoko tsa litsebi tse sebetsang ka thepa ena. Ho utloisisa litšobotsi tsa eona ke senotlolo sa ts'ebetsong e atlehileng ho liindasteri tse fapaneng.

Ho utloisisa Powder e Phahameng ea Silicon Carbide

Bohloeki bo phahameng ba silicon carbide phofo, eo hangata e bitsoang SiC powder, ke mofuta oa crystalline oa silicon carbide e nang le litšila tse fokolang. Bohloeki bona bo phahameng bo bohlokoa bakeng sa ts'ebetso ea eona lits'ebetsong tse hlokang. Boemo ba bohloeki hangata bo hlahisoa e le liperesente tsa litaba tsa SiC, 'me liperesente tse phahameng li bonts'a litšila tse nyane. Thepa ea phofo, joalo ka kabo ea boholo ba likaroloana, morphology le sebaka sa bokaholimo, li fapana haholo ho latela mokhoa oa tlhahiso. Thepa ena e ama ka ho toba lits'ebetso tsa eona tsa ho qetela.

Mekhoa ea Tlhahiso ea Phofo e Phahameng ea Silicon Carbide Powder

Mekhoa e mengata e sebelisoa bakeng sa tlhahiso ea bohloeki bo phahameng ba silicon carbide phofo. Tse atileng haholo li kenyelletsa:

Mokhoa oa Acheson

Ts'ebetso ea Acheson ke mokhoa oa khale o kenyelletsang karabelo e phahameng ea mocheso oa silika (SiO₂) le carbon (C) ka seboping sa motlakase. Ts'ebetso ena e fana ka likristale tsa SiC tsa boholo bo fapaneng le libopeho. Le hoja e batla e le theko e tlaase, e hlahisa phofo e nang le bohloeki bo fokolang ha e bapisoa le mekhoa e meng.

Kemiso ea Mouoane oa lik'hemik'hale (CVD)

CVD ke mokhoa o sebelisoang haholo ho hlahisa bohloeki bo phahameng ba silicon carbide phofo e nang le boholo bo laotsweng le mofoloji. Li-precursor tsa gaseous, joalo ka silane (SiH₄) le methane (CH₄), itšoara ka mocheso o phahameng ho etsa likaroloana tsa SiC. Mokhoa ona o lumella ho laola ka nepo litšoaneleho tsa phofo, ho etsa hore e be se loketseng bakeng sa lits'ebetso tse khethehileng. CVD e boetse e lebisa ho litšila tse fokolang ho feta mokhoa oa Acheson.

Mekhoa e Meng

Mekhoa e meng, joalo ka sol-gel synthesis le phokotso ea carbothermal, e boetse e sebelisoa ho kopanya SiC e hloekileng haholo. Mekhoa ena e fana ka melemo e ikhethang ho latela litlhoko tse khethehileng tsa boholo ba likaroloana, sebopeho le bohloeki.

Lisebelisoa tsa High Purity Silicon Carbide Powder

Thepa e ikhethang ea bohloeki bo phahameng ba silicon carbide phofo etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo, ho kenyelletsa:

Indasteri ea Semiconductor

Indasteri ea semiconductor, SiC e sebelisetsoa ho etsa li-substrates bakeng sa lisebelisoa tsa elektronike tse matla le tse phahameng haholo. The high conductivity thermal conductivity and wide bandgap of SiC thusa hore ho hahoe lisebelisoa tsa elektronike tse sebetsang hantle le tse tšepahalang.

Li-abrasives

Ka lebaka la ho thatafala ha eona le botsitso bo phahameng ba mocheso, bohloeki bo phahameng ba silicon carbide phofo e fumana tšebeliso e pharaletseng e le ntho e senyang lithulusi tsa ho seha, mabili a silang, le metsoako ea ho bentša. Bokhoni ba eona bo phahameng ba ho itšeha ha bo bapisoa le li-abrasives tse ling bo etsa hore e be khetho e ratoang lits'ebetsong tse fapaneng tsa indasteri.

Refractories

Boemo bo phahameng ba ho qhibiliha ha SiC le ho se sebetse ha lik'hemik'hale ho kenya letsoho tšebelisong ea eona ho li-refractories, lisebelisoa tse ka mamellang mocheso o phahameng haholo. Sena se bohlokoa haholo lits'ebetsong tse kang libopi tsa metallurgical le li-reactors tsa mocheso o phahameng.

Ceramics le metsoako

Bohloeki bo phahameng ba silicon carbide phofo ke karolo ea bohlokoa ho li-ceramics le li-composites tse tsoetseng pele, tse alimang matla a phahameng, boima le ho hanyetsa lihlahisoa tsa ho qetela. Sena se kenya letsoho lits'ebetsong tse fapaneng tse kang ho roala lihlomo le likarolo tsa indasteri.

Ho Khetha Powder ea Silicon Carbide e nepahetseng ka ho Fetisisa

Khetho e nepahetseng bohloeki bo phahameng ba silicon carbide phofo e itšetlehile ka litlhoko tse khethehileng tsa kopo. Lintlha tsa bohlokoa tse lokelang ho nahanoa li kenyelletsa:

Bakeng sa boleng bo holimo bohloeki bo phahameng ba silicon carbide phofo le lihlahisoa tse amanang le tsona, nahana ka ho hlahloba likhetho ho tsoa ho barekisi ba tšepahalang joalo ka Inner Mongolia Xinxin Silicon Industry Co.,Ltd. Ba fana ka mefuta e fapaneng ea lihlahisoa tse etselitsoeng ho fihlela litlhoko tse fapaneng tsa indasteri.

Qetello

Bohloeki bo phahameng ba silicon carbide phofo ke sesebelisoa se feto-fetohang se nang le lits'ebetso tse ngata tsa mahlale a tsoetseng pele. Ho utloisisa thepa ea eona, mekhoa ea tlhahiso, le lits'ebetso tse fapaneng ke senotlolo sa ho sebelisa matla a eona a felletseng ho liindasteri tse fapaneng. Khetho ea kereiti e loketseng e hloka hore ho nahanoe ka hloko litlhoko tse khethehileng tsa kopo ka 'ngoe. Ka ho nahanisisa ka lintlha tsena ka hloko, litsebi li ka etsa bonnete ba hore thepa ena e tsotehang e sebelisoa ka katleho.

Tlhokomeliso: Lintlha tsena ke tsa tsebo e akaretsang 'me ha lia lokela ho nkoa e le keletso ea setsebi. Ikopanye le litokomane tse amehang tsa tekheniki le litsebi bakeng sa lits'ebetso tse ikhethileng.
