Silicon carbide crucible ke sejana se sebetsang hantle haholo se sebelisoang haholo indastering ea ho qhibilihisa le ho lahla tšepe. Ho hanyetsa mocheso oa eona o phahameng haholo le bophelo bo bolelele ba ts'ebeletso li etsa hore e sebetse hantle haholo libakeng tse fapaneng tse thata tsa ho sebetsa. Ha li bapisoa le li-crucibles tse tloaelehileng tsa graphite, li-silicon carbide crucibles ha li na feela molumo o moholo le bophelo bo bolelele, empa hape li bontša ntlafatso e kholo likarolong tse ngata tsa ts'ebetso.

Ithute ka premiumSilica Cruciblese etselitsoeng ho qhibilihisa tšepe ea mocheso o phahameng. Ea ronali-crucibles tsa silicon carbidefana ka conductivity e phahameng ea mocheso, ho hanyetsa kutu, le nako e telele ea bophelo. E nepahetse bakeng sa lisebelisoa tsa koporo le aluminium.

Melemo ea ho Sebelisa Silica Crucibles

Li-crucible tsa silika li ikhetha ka thepa ea tsona e ikhethang:

Boima bo phahameng ba mocheso: Ho fetisoa ha mocheso ka potlako le ka mokhoa o ts'oanang ho tiisa nako ea ho qhibiliha ka potlako le katleho e phahameng.
Bophelo ba tšebeletso bo atolositsoeng: Li-silica crucibles li nka nako e telele ea 2-5 ho feta li-crucible tsa letsopa tsa graphite, ho fokotsa makhetlo a mangata.
