Ho utloisisa Phapang lipakeng tsa Clay Graphite Crucibles le Graphite Silicon Carbide Crucibles

likotlolo tsa letsopa

Ha ho etsoa liteko tsa lik'hemik'hale tse phahameng tsa mocheso kapa lisebelisoa tsa indasteri, khetho ea thepa ea crucible e phetha karolo ea bohlokoa ho netefatsa katleho le polokeho ea ts'ebetso. Mefuta e 'meli e sebelisoang hangata ea li-crucibles kelikotlolo tsa letsopa tsa graphitelegraphite silicon carbide crucibles. Ho utloisisa sebopeho sa eona sa thepa, mocheso oa refractory, inertness ea lik'hemik'hale, le conductivity ea mocheso ho bohlokoa ho etsa qeto e nang le tsebo ha ho khethoa crucible e loketseng bakeng sa litlhoko tse itseng tsa laboratori kapa indasteri.

motsoako oa lintho tse bonahalang:
Clay graphite crucible haholo-holo e entsoe ka graphite, letsopa le tekanyo e itseng ea lubricant, 'me e tsebahala ka ho se sebetse ha lik'hemik'hale. Ka lehlakoreng le leng, graphite silicon carbide crucible e entsoe ka silicon carbide powder le li-oxide tse ling tse sa tloaelehang tsa lefats'e, 'me e na le litšobotsi tsa ho hanyetsa mocheso o phahameng, ho hanyetsa mocheso o matla haholo, le ho se sebetse ha lik'hemik'hale tse phahameng.

Mocheso oa ho hanyetsa mollo:
Thempereichara ea refractory ea letsopa graphite crucibles ka kakaretso fihla hoo e ka bang 1200 ° C, ha graphite silicon carbide crucibles ka mamella mocheso ka holimo 1500 ° C. Sena se etsa hore graphite silicon carbide crucibles e be e loketseng haholoanyane bakeng sa lits'ebetso tse hlokang mocheso o phahameng litekong tsa lik'hemik'hale le lits'ebetsong tsa indasteri.

Inert ea lik'hemik'hale:
Mefuta ena ka bobeli ea li-crucible e bonts'a tekanyo ea ho se sebetse ha lik'hemik'hale, e lula e tsitsitse ka har'a litharollo tse ngata tsa asiti, alkali le letsoai 'me e hanela ho bola. Leha ho le joalo, karolo ea letsopa ka li-crucibles tsa letsopa tsa graphite e etsa hore ho be bonolo ho monya likarolo le litšila ha li bapisoa le graphite silicon carbide crucibles.

Thermal Conductivity:
Graphite e na le conductivity e phahameng ea mocheso 'me e ka senya mocheso kapele. Leha ho le joalo, ka lebaka la sebopeho se hlephileng sa letsopa la graphite crucible, matheba a matšo a atisa ho hlaha holim'a eona 'me a hloka ho hloekisoa khafetsa. Ka lehlakoreng le leng, li-crucible tsa graphite silicon carbide li na le conductivity e tlaase ea mocheso 'me li ke ke tsa siea matheba holim'a metsi. Ho phaella moo, boima ba bona bo phahameng bo thibela ho roala le ho senyeha.

Khetha crucible e nepahetseng:
Ha u khetha crucible ea laboratori ea lik'hemik'hale, litlhoko tse khethehileng li tlameha ho nkoa. Clay graphite crucibles e loketse liteko tse akaretsang tsa k'hemistri, athe graphite silicon carbide crucibles e loketse liteko tse hlokang mocheso o phahameng le maemo a boima haholo. Ke habohlokoa ho latela ka tieo litaelo tsa tšebeliso ho qoba ho hlōleha ha liteko ka lebaka la ts'ebetso e sa lokelang.

Ka bokhutšoanyane, ho utloisisa phapang pakeng tsa letsopa la graphite crucibles le graphite silicon carbide crucibles ke habohlokoa ho khetha crucible e nepahetseng ka ho fetisisa bakeng sa laboratori e itseng kapa kopo ea indasteri. Ka ho nahana ka lintlha tse kang mocheso oa refractory, inertness ea lik'hemik'hale le conductivity ea mocheso, bafuputsi le litsebi tsa indasteri ba ka etsa liqeto tse nang le tsebo ho netefatsa katleho le polokeho ea liteko le mekhoa.
