The Rare Metal Smeltering Crucible is primarily used for the distillation of zinc oxide and the smelting of copper, gold, silver, and other rare metals. It is also suitable for smelting middle alloy and master alloy. The crucible is designed to offer better thermal resistance than normal isostatic-pressed crucibles and effectively resists erosion from zinc vapor. It can withstand the corrosive environment caused by chemical additives during the smelting process.
Applicable melting point ranges from 900 to 1400°C. Compatible with gas ovens, oil ovens, coke ovens, and induction ovens.
