Description
Specifications

Tungsten crucible is used to grow monocrystals (Read more about crystal growing machines on the website page gkmp32.com) for melting, sintering and annealing of powder materials, melting of quartz, rare-earth and refractory metals, and to deposit metallic film in vacuum (the temperature inside a furnace is over 2000°С).

Tungsten crucibles are widely used in metallurgy, metalwork, iron work and chemical industry. However, the most important role tungsten plays in leucosapphire crystal production; high density and purity, no internal cracks and perfectly smooth surface are crucial for quality crystal growing.

The key advantage of our tungsten crucible is that we can delivera customized crucible of any shape or size per Customer’s requirement: circular, rectangular, elliptic, V-shaped, cover-equipped, etc.  

The price of a tungsten crucible is conditioned by specific production of tungsten units (tungsten is quite complicated to obtain in pure and rather hardly processed). Apart from that, the price of crucible depends on complexity and configuration, as well as from possible auxiliary requirement that may be imposed.

Technical characteristics:

  • High tungsten purity – above 99.95%;
  • High density – 18.2 g/cm3;
  • Surface roughness - Rz 6.3 max

Tungsten crucible is reliable and durable, has a high strength and elasticity, fit to withstand high temperatures in vacuum and inert gases (up to 2600°С).

Tungsten crucibles for melting are produced by different methods depending on their application purpose:

 
 
  • Powder sintering (used for crucibles of any shape and dimensions);
  • Turning (complex machining of workpieces);
  • Plasma sputtering
