Pure tungsten is used to make tungsten crucibles, which have the same properties as pure tungsten. It is a crucial component of the thermal field for sapphire crystal development, the smelting of rare earths, the continuous melting of quartz, and the high temperature heat treatment furnace. Under 2600°C, it can be employed in vacuum or inert gas.
We can offer crucibles with ordinary density (about 18.3 g/cm3) and high density (about 18.5 g/cm3) according on the needs of the customer. The interior surface is flawless and unblemished, so even at high temperatures, the contents inside the container won't be harmed. The crucible's deformation resistance has been greatly increased after special processing.
