The Use of Molybdenum and Tungsten in Crucibles

Jan 09, 2013 · PLANSEE's pressed-sintered crucibles are made from tungsten or molybdenum and have a surface roughness of below 0.8 µm. when the crucible's surface is rough, the sapphire cannot be easily extracted and this tends to damage the crystal. Besides, the crucible also gets damaged in the process.
