Tungsten Crucible For Single Crystal Growth Furnace

1. Tungsten Crucible For Single Crystal Growth Furnace Description:

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.

4. Production Process of Tungsten Crucible For Single Crystal Growth Furnace:


One of the most important preparation methods for industrial production of tungsten crucibles today is the sintering method. The sintered tungsten crucible is first assembled into the mold according to the size required by the product, and then the tungsten powder raw materials that meet the national standard are loaded into the mold and sealed. The next step is to put it into an isostatic press with a pressure of 180-250MPa to start the pressing operation, and then put the green compact into a high-temperature induction sintering furnace with a heating rate of 80-150℃/h for sintering, and the high temperature holding time Best for 4-8 hours. Finally, it is processed according to the product requirements. After processing, the quality inspection of the appearance, size, density, etc. of the finished product is carried out.
5. Advantage of Tungsten Crucible For Single Crystal Growth Furnace:

The raw material used in the sintered tungsten crucible is tungsten powder. After forming by firing, the tungsten crucible is obtained by lathe processing. The biggest advantage of the sintered tungsten process is that it can produce large-sized tungsten crucibles. Sintered tungsten crucibles are preferred by many producers because they have a longer service life, a more consistent quality, and greater diameters as compared to stamped tungsten crucibles. The preparation technology of large-size sintered crucibles in my country has reached the international advanced level, and the quality and production capacity of this type of tungsten crucibles are also at a high level.
