Formed Molybdenum and Tungsten Crucibles

Featured Product from Plansee SE


Tungsten and molybdenum crucibles:
Thin wall. High performance.

Formed molybdenum and tungsten crucibles excel in the so-called HEM process (Heat Exchanger Method). They are the perfect vessels for melting and solidifying the single crystal. Our formed crucibles have particularly thin walls combined with excellent creep resistance. The outstanding purity of our material prevents any contamination of the single crystal. Even the most aggressive sapphire melts cannot do any harm to our materials.

We produce large numbers of formed molybdenum and tungsten crucibles which we can supply in all commonly used dimensions. They are successfully used by all the major manufacturers and numerous end customers worldwide. We produce the input material for our crucibles ourselves in our in-house hot rolling mill for refractory metals. This is where we manufacture the world's largest molybdenum and tungsten sheets which will enable us to continue producing very large dimensions in the future.
