Ngoko ke, kubalulekile ukuvavanya indawo yeekhemikhali kwaye ukhethe i-crucible ene-corrosion resistance resistance ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide.

Ukusetyenziswa ngokufanelekileyo kwe-graphite silicon carbide crucibles kubalulekile ekwandiseni ubomi babo benkonzo. Ukusetyenziswa okungafanelekanga, okufana nokubeka i-crucible kwiinguqu zokushisa ngokukhawuleza okanye ukulahla izinto ezibandayo kuyo, kunokuchaphazela kakhulu ukuqina kwayo. Ukulandela izikhokelo zokusetyenziswa ezicetyiswayo kunye neenkqubo zokuphatha kubalulekile ekwandiseni ubomi be-crucible yakho kunye nokuthintela ukunxitywa kwangaphambili kunye nomonakalo.

Ukubambelela kunye nobukho be-oxide layers kwi-crucible nayo inokuchaphazela ukusebenza kwayo kunye nobomi benkonzo. Ukucoca rhoqo kunye nokugcinwa kokususa nayiphi na i-adhering or oxidized layers ibalulekile ukuqinisekisa ubude kunye nokusebenza kakuhle kwe-crucible yakho.

Xa uvavanya ubomi benkonzo ye-graphite silicon carbide crucibles, kubalulekile ukuqwalasela iimeko ezithile zokusebenza kunye nommandla wokusetyenziswa. Ubomi benkonzo bunokwahluka ngokusekelwe kwizinto ezifana nobushushu, ukuvezwa kweekhemikhali, kunye neendlela zokusetyenziswa. Uvavanyo kunye novavanyo kufuneka lwenziwe rhoqo ukugqiba ubomi benkonzo yangempela ye-crucible kunye nokuchonga naziphi na iimpawu zokuguga okanye ukuwohloka.

Isishwankathelo, ukwandisa ubomi benkonzo ye-graphite silicon carbide crucibles kufuna ukuqwalasela ngokucophelela izinto ezahlukeneyo, kubandakanywa ukushisa okusebenzayo, ukusetyenziswa rhoqo, indawo yeekhemikhali, ukusetyenziswa ngokufanelekileyo kunye nokuhlolwa kwexesha. Ngokubambelela kwiindlela ezicetyiswayo zokusetyenziswa kunye nokwenza ukugcinwa kwesiqhelo, unokwandisa ubomi bezi zibonda, uqinisekise ukusebenza okusebenzayo kunye nokuthembekileyo kwi-metal cast kunye nezicelo zokunyibilika.

 

 

Ubomi benkonzo ye-graphite silicon carbide crucibles buhlala bungumxholo oxhalabisayo kwishishini lezinto eziphathekayo njengoko ezi zixhobo zidlala indima ebalulekileyo kwiintlobo ezahlukeneyo zokushisa okuphezulu ezifana nokuphosa isinyithi, ukuveliswa kweglasi kunye nophando lwebhubhoratri. Uphononongo lwakutsha nje olwenziwe ngoososayensi bezinto ezibonakalayo lubonisa izinto ezichaphazela ubomi benkonzo yezi crucibles kwaye zibonelela ngeembono ezixabisekileyo ekuphuculeni ukuqina nokusebenza kwazo.

I-graphite silicon carbide crucibles iyaziwa ngokugqithiswa kwe-thermal conductivity, ukuxhathisa ukothuka okuphezulu kwe-thermal kunye nokungangeni kwekhemikhali eyomeleleyo, izenza zilungele ukumelana namaqondo obushushu agqithisileyo kunye nemo engqongileyo yeekhemikhali eziqatha.
