Sintered tungsten crucible
Sintered with tungsten powder the sintered tungsten crucibles are multi-purpose production in sintering furnace, large crystal growth furnace. Thickness of sintered tungsten crucibles is usually 8-12 mm; diameter is typically 100-550 mm; height is typically 50-700 mm. Such crucible Purity: W ¡Ý 99.95%; density is usually up 18.2g/cm3, by special needs the density can up 18.8g/cm3 or more.
Features:
1.The overall density of sintered tungsten crucible is fairy high between 18g/cm3 to 18.3g/cm3;
2.Its chemical purity of sintered tungsten crucible can be above 99.95%;
3.The diameter of sintered tungsten crucible can be above 200mm;
4.The surface roughness of tooled crucibles does not exceed Rz 6.3;
5.The use temperature of sintered tungsten crucible should be below 2450oC in vacuum or deoxidize atmosphere.
6. The shapes and dimensions of crucibles are also made in accordance with customers' requirements.
