sapphire ingot growing furnace tungsten crucible

sapphire ingot growing furnace tungsten crucible
Product Detailed
tungsten crucible for crystal growing furnace specifiction: OD350 X H450mm Composition: tungsten >99.95% Density >18g/cc

Tungsten has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Molybdenum also belongs to the refractory metals group with excellent thermal properties and is still easy to machine. So , tungsten, molybdenum and their alloy is the best choice for the all kinds of high temperature furnace. They can easily withstand even the most intense heat.
