Production method of body material crucible for calcining hydroxides in tantalum and niobium smelting
The invention discloses a production method of a body material crucible for calcining hydroxides in tantalum and niobium smelting. The production method includes the steps of material blending, primary moulding, primary hydraulic treatment, vacuumizing packaging with plastic membrane, primary isostatic pressing treatment, microwave drying, and high-temperature roasting. The production method is stable in moulding. A crucible product is uniform in shape and wall thickness and is excellent in compactness. The production method is convenient and quick, is simple in operations, saves labor intensity and manual work, is less in investment cost, is short in production period, allows batched production and can reduce labor cost.
