I-graphite crucible, eyaziwa ngokuba yi-alten copper ladle, ubhedu olutyhidiweyo, njl. Iicrucibles zegraphite zisetyenziselwa ukunyibilikisa ubhedu, ubhedu, igolide, isilivere, i-zinc kunye nelothe kunye nezinye iintsimbi ezingenayo i-ferrous kunye ne-alloys yazo.
I-Graphite crucible yenziwe nge-flake yendalo ye-graphite njengeyona nto iphambili ekrwada kunye nodongwe olulahlisiweyo lweplastiki okanye i-carbon njengesibophelelo. Uneempawu zokumelana nobushushu obuphezulu, ukuqina kwe-thermal conductivity, ukuchasana kakuhle kwe-corrosion kunye nobomi benkonzo ende. Kwinkqubo yokusetyenziswa kweqondo lokushisa eliphezulu, i-coefficient yokwandiswa kwe-thermal incinci, kwaye inobunzima obuthile bokumelana nokubanda ngokukhawuleza kunye nokushisa okukhawulezayo. Inokumelana ne-corrosion eqinile kwizisombululo ze-acidic kunye ne-alkaline, inozinzo oluhle kakhulu lweekhemikhali, kwaye ayithathi nxaxheba kuyo nayiphi na i-chemical reactions ngexesha lenkqubo yokunyibilikisa. Udonga lwangaphakathi lwe-graphite crucible lugudileyo, kwaye ulwelo olutyhidiweyo alukho lula ukuvuza kwaye lunamathele eludongeni lwangaphakathi lwe-crucible, ukwenzela ukuba isinyithi esilulwelo sibe ne-fluidity elungileyo kunye nokuphosa, kwaye ifanelekile ukuphosa kwiimbumba ezahlukeneyo. . Ngenxa yezi mpawu zibalaseleyo ezikhankanywe ngasentla ze-graphite crucible, isetyenziselwa ngokubanzi ukunyibilikisa insimbi yensimbi yensimbi kunye nokunyibilikisa izinyithi ezingenayo i-ferrous kunye ne-alloys yazo.
