High-temperature melting usually involves the preparation of metals, rare earth elements or special alloys with high melting points, and the process environment is harsh, and the requirements for container materials are extremely high. With its unique properties, tungsten crucible has become the preferred container for high-temperature smelting, and its application involving metallurgy, aerospace, rare earth smelting and other industries.

The main properties of tungsten crucible include high melting point, high temperature resistance, excellent corrosion resistance, good thermal shock stability, and high strength and stability.

Tungsten crucibles are used in a wide range of applications due to their extremely high melting point, excellent high-temperature strength, good thermal conductivity and strong chemical inertness in vacuum or inert atmospheres.

Tungsten crucible is a kind of high-temperature container made of tungsten (W) or tungsten-based alloy as the main material, which is widely used in metallurgy, materials science, semiconductor, aerospace and other fields that require ultra-high temperature treatment.
