ukuncibilika komlilo wethusi we-graphite crucible ukuthi ungakhetha kanjani?

Ithusi elincibilikisa i-graphite crucible / i-silicon carbide crucible encibilikisa igolide ehlukahlukene, isiliva, ithusi, i-aluminium, umthofu, i-zinc nezinye izinsimbi ezingenayo insimbi, insimbi ye-carbon steel, izinsimbi ezihlukahlukene ezingavamile kanye nemikhiqizo ye-carbon. Ifanele ukuncibilika kwensimbi ezithandweni ezingaphansi komhlaba, ezithandweni zikagesi, amafrikhwensi aphakathi nendawo kanye neziko eliphezulu.

1. Ukumelana okuhle kokushisa okuphezulu kwe-crucible yethusi ye-graphite encibilikisiwe, izinga lokushisa elincibilikayo lingafinyelela ku-1800 ° C;

2. I-conductivity enhle yokushisa ye-graphite crucible yethusi elincibilikisiwe ine-coefficient encane yokwandisa ukushisa, ingakwazi ukuqhuba ukushisa ngokushesha, futhi inokumelana okuqinile kokucindezeleka ekushiseni okusheshayo nokucisha;

3. Ukuzinza kwamakhemikhali okuhle kakhulu kwe-crucible ekhethekile yokuncibilikisa ithusi kunokumelana nokugqwala okuqinile kuzixazululo ze-asidi ne-alkaline.
