Although tungsten itself has excellent thermal stability and corrosion resistance, the actual service life of tungsten crucibles is affected by a number of factors. Therefore, a lifetime assessment of the system not only helps to improve the efficiency of equipment operation, but also reduces material waste and maintenance costs.

As an important part of the process of carrying molten metal, crystal growth, high-temperature evaporation, etc., tungsten crucible must not only have excellent high-temperature stability and chemical inertness, but also have good heat transfer performance to ensure the thermal efficiency of the process and the uniformity of temperature control.

Tungsten crucible is one of the typical applications of tungsten material, in addition to the performance of the material itself, the influence of machining accuracy on the final performance of the crucible can not be ignored, especially in the context of increasingly strict requirements for high-precision manufacturing and thermal field control, processing quality has become one of the key factors to evaluate the reliability and practicability of the crucible.

Tungsten crucibles are widely used in sapphire crystal growth, rare metal smelting, high-temperature material testing and other fields due to their excellent high-temperature stability and corrosion resistance.
