Product Description
99.95% W Tungsten Materials Crucible Heating Elements Of Induction Furnace
A tungsten crucible is made of pure tungsten as raw material and has the same characteristics as pure tungsten. It is an important container for sapphire crystal growth thermal field, rare earth smelting, quartz continuous melting, and high-temperature heat treatment furnaces. It can be used in vacuum or inert gas below 2600°C.
