Tungsten is resistance to certain molten metals and metal oxides, and it is high-temperature resistance, low pollution. Tungsten crucible is widely used in technologies for growing monocrystals from molten corundum, it is also used in electronics and technologies for thermal vaporization-deposition of various substances. It is an important part of the high-temperature furnace cause its high melting point.
Tungsten crucible and other pure tungsten & molybdenum parts can be used for sapphire crystal growth and rare-earth melting due to their and other excellent characteristics.

|Other dimensions can be customized, we can also provide rectangular crucible.|
Tungsten crucibles have been widely used in technologies for growing single crystals from molten corundum, as well as in electronics and technologies for thermal vaporization – deposition of various substances.
Our tungsten crucibles are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
