to have high heat resistance, evaporation resistance and structural stability. With its unique properties, tungsten crucible plays an irreplaceable role in high-temperature precision processes including aerospace, semiconductors, special alloys, rare earth metallurgy, etc.

As an important refractory metal product in the field of high temperature, tungsten crucible plays a key role in the fields of metallurgy, semiconductor, aerospace and nuclear energy. In order to ensure its reliability and safety in extreme environments, it is particularly important to test and analyze the mechanical properties of the system. 

Tungsten crucibles operating in high-temperature environments must have good thermal stability and thermomechanical compatibility, especially when used with other structural materials (such as graphite, ceramic, quartz glass), and its coefficient of thermal expansion (CTE) becomes a key factor in the design and use process.

Superalloy is a kind of alloy material that can maintain excellent mechanical properties and corrosion resistance in a high-temperature environment, and is widely used in aerospace, gas turbine, nuclear energy equipment and other fields. Due to the generally high melting point of superalloys, some even exceeding 1500 °C, the preparation process puts forward extremely strict requirements for the high temperature resistance, chemical stability and structural strength of the container material.
