As an indispensable key material in the high-temperature industry, the performance of tungsten crucible directly affects the production efficiency and product quality in many fields such as crystal growth, metal melting and vacuum evaporation. Among the many performance indicators, the purity level of tungsten material not only determines the physical properties of the crucible, but also has a profound impact on its chemical stability, mechanical strength and service life.

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.

Tungsten crucibles are widely used in crystal growth, metal smelting and vacuum evaporation processes. However, in the high-temperature oxidation environment, its performance has certain particularities and limitations, which has become an important issue that must be paid attention to in its practical application.

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.
