High Purity 99.95% Tungsten Crucible

Description: tungsten crucible
Tungsten crucible is one of metal tungsten products, which can be formed by sintering, stamping and spinning. Sintering products manufactured under the guidance of powder metallurgical technology is the most commonly used type for furnaces. Tungsten crucibles are specially made from pure tungsten plates or tungsten rods in corresponding processes, such as machine shaping and welding farbrication. tungsten crucible

Application: tungsten crucible

1.Tungsten crucibles are widely used as core containers in sapphire crystal growth furnace, quartz glass melting furnace, rare-earth smelting furnace and other industrial furnaces since the melting point of tungsten is as high as 3410℃;
2.Tungsten crucible can greatly benefit the crystal success rate, quality control in pulling crystal process as well as the service life of sapphire crystal growth furnace. tungsten crucible
