Product Details

Tungsten crucible is a type of container made from tungsten, a rare, hard, and dense metal with the highest melting point of all elements (approximately 3,422 degrees Celsius or 6,192 degrees Fahrenheit). Tungsten crucibles are used for high-temperature applications, such as in metallurgy, ceramics production, and for the synthesis of materials that require a non-reactive and refractory container.

Features of tungsten crucibles

High melting point: As mentioned, tungsten has the highest melting point of any element, allowing the crucible to be used for processes involving extreme temperatures.

Corrosion resistance: Tungsten does not react with most molten metals and is resistant to corrosion from many chemical agents, making it ideal for containing reactive melts.

Low coefficient of thermal expansion: Tungsten crucibles have a low coefficient of thermal expansion, which means they are less likely to crack or break when subjected to rapid temperature changes.

Good thermal conductivity: Tungsten is a good conductor of heat, allowing for more uniform heating of its contents.

Durability: Tungsten is a very strong material, giving tungsten crucible the ability to withstand mechanical stress without deforming.

Applications of tungsten crucibles

Metal refining: Used in the refining process of metals such as steel, where high temperatures are required to achieve the desired purity.

Chemical analysis: In X-ray fluorescence (XRF) spectrometers, for sample preparation where the crucible can hold the sample during analysis.

Ceramic processing: For firing ceramics at high temperatures, where traditional crucible materials would not be able to withstand the heat.

Synthesis of high-temperature materials: For example, the creation of superalloys or other advanced materials requiring controlled, high-temperature environments.
