Carbon bonded silicon carbide crucible, e sebelisoa haholo lilaboratoring tsa mocheso o phahameng. Li-crucibles tsena li fana ka melemo e fapaneng e kang matla a phahameng le ho hanyetsa deformation le ho robeha ha mocheso o phahameng. Leha ho le joalo, ke habohlokoa ho hlokomela hore ba boetse ba na le mefokolo e itseng e lokelang ho nahanoa.
E 'ngoe ea likotsi tse ka sehloohong tsa li-silicon carbide crucibles ke ho fokola ha tsona. Li-crucibles tsena li tloaetse ho robeha ha li ts'oaroa ke ts'ebetso ea mochini nakong ea ts'ebeliso. Hang ha e senyehile, e ka etsa hore liteko li hlolehe kapa li sekisetse ho nepahala ha data ea liteko. Bofokoli bona bo lokela ho tsotelloa 'me ho nkoe mehato e nepahetseng nakong ea ts'ebetso le ts'ebeliso.
Phoso e 'ngoe ea li-silicon carbide crucibles ke hore li na le tloaelo ea ho ba le oxidation ka mocheso o phahameng. Ha e pepesehetse mocheso o phahameng, lesela la oxide le ka theha holim'a crucible, e ka sitisang liphello tsa liteko. Ke habohlokoa ho thibela oxidation ena ka ho nka mehato ea tšireletso, e kang ho koahela holim'a crucible ka lera le sireletsang.
Ntle le moo, li-crucibles tsa silicon carbide li na le mefokolo e itseng ka lebaka la lintlha tse kang ts'ebetso ea tlhahiso le litšenyehelo. Meeli ena e ka fokotsa boholo, sebopeho le bokhoni ba crucible. Ka hona, bafuputsi le bahlahisi ba hloka ho nahana ka meeli ena ha ba khetha li-crucible bakeng sa litlhoko tsa bona tse ikhethileng.
Ho rarolla mefokolo ea silicon carbide crucibles, ho na le litharollo tse 'maloa. Ntlha ea pele, e le ho ntlafatsa bophelo ba ts'ebeletso ea crucible, mekhoa e ka sebelisoa ho matlafatsa ts'ehetso ea lerako la ka hare ho etsa hore e se ke ea hlola e apara le ho tšoarella. Sena se thusa ho thibela ho robeha le ho lelefatsa bophelo ba crucible.
Ea bobeli, e le ho thibela oxidation, lesela le sireletsang le ka sebelisoa holim'a crucible. Lera lena le thibela crucible ho itšoara ka oksijene ka mocheso o phahameng, kahoo e thibela ho thehoa ha lesela la oxide.
Qetellong, ho hlola mefokolo ea li-crucible tsa silicon carbide, moralo o ka ntlafatsoa le mekhoa e tsoetseng pele ea tlhahiso e amoheloang. Ka ho etsa joalo, ho ka etsoa libopeho tse kholoanyane, tse tebileng, le tse rarahaneng, tse lumellang tšebeliso ea li-crucibles tsena ka mefuta e mengata ea litlhophiso tsa liteko. Ho feta moo, lisebelisoa tse ling tse kang li-ceramics tsa mocheso o phahameng li ka nkoa li nka sebaka sa silicon carbide crucibles.
Qetellong, li-crucibles tsa silicon carbide li na le mefokolo e itseng, empa ts'ebeliso ea tsona ka laboratoring e ntse e le molemo haholo. Kakaretso ea ts'ebetso le ho feto-fetoha ha li-silicon carbide crucibles li ka ntlafatsoa ka ho nka mehato e nepahetseng le ho ntlafatsa ho sebetsana le brittleness ea bona, ho ba bonolo ho oxidation le mefokolo. Bafuputsi le bahlahisi ba lokela ho nahana ka lintlha tsena ka hloko ha ba khetha li-crucibles tsa liteko tsa mocheso o phahameng.
