Crucibles for crystal growth

Tungsten/ molybdenum crucible

For various single crystal growths, tungsten/ molybdenum crucibles are most suitable.
We can offer both sintered products and spinning products according to the growing single crystal method. We can also manufacture very large products (drawing product: D600 x H600 mm)
Feature a long life even after repeated use, because of high density and uniform metal structure; these are widely used as crucibles for pulling single crystal sapphire, in particular.
