Ukunyibilika kweziko lobhedu lwe-graphite crucible indlela yokukhetha?

Ubhedu olunyibilikayo lwe-graphite crucible / i-silicon carbide crucible inyibilikisa igolide eyahlukeneyo, isilivere, ubhedu, i-aluminiyam, ilothe, i-zinc kunye nezinye iintsimbi ezingenayo i-ferrous, intsimbi yekhabhoni ephakathi, iintsimbi ezahlukeneyo ezinqabileyo kunye neemveliso zekhabhoni. Ilungele ukunyibilikiswa kwesinyithi kwiziko eliphantsi komhlaba, kwiziko lombane, iziko eliphakathi kwamaza ombane kunye neziko eliphezulu.

1. Ukumelana nokushisa okuphezulu okuphezulu kwe-crucible copper graphite crucible, ubushushu obunyibilikayo bunokuba buphezulu malunga ne-1800 ° C;

2. Ukuqhuba kakuhle kwe-thermal ye-graphite crucible kwi-copper etyhidiweyo ine-coefficient encinci yokwandisa i-thermal, inokuqhuba ubushushu ngokukhawuleza, kwaye inamandla okumelana nokushisa ngokukhawuleza kunye nokucima;

3. Ukuzinza kweekhemikhali okugqwesileyo kwe-crucible ekhethekileyo yokunyibilikisa ubhedu kunokumelana ne-corrosion eqinile kwi-acid kunye ne-alkaline solutions.
