In the actual use process, tungsten crucibles often face the risk of crack formation, which not only affects its service life, but also directly affects the stability of the process and product quality.

Tungsten crucible is widely used in high-temperature vacuum processes such as crystal growth, rare metal smelting and vacuum evaporation due to its high temperature resistance, thermal shock resistance and strong chemical inertness.

Tungsten crucible plays an important role in the process of crystal growth, such as bearing molten raw materials, high-temperature heat transfer and environmental isolation, and its reasonable design directly affects the quality, yield and stability of the whole process. Therefore, it is of great significance to carry out the optimal design of the crucible according to the special working conditions of the crystal growth furnace.

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.
