What are the areas of tantalum crucible?

Tantalum crucible has good high temperature resistance, corrosion resistance, deformation resistance and other properties, mainly including the following aspects:

1. Chemical experiment and Analysis field:

In the chemical laboratories of universities, scientific research institutions and enterprises, tantalum crucible is often used for high temperature heating, burning, melting and other operations of various chemical substances, which can be used to analyze the composition of some substances and conduct the synthesis and decomposition experiments of substances. For example, when analyzing the metal content in ore, soil and other samples, tantalum crucible may be used to pretreat the samples.

Because tantalum crucible has strong corrosion resistance to most chemical reagents, tantalum crucible is an ideal container choice in the treatment process of some strong corrosive chemicals, such as concentrated acid and strong alkali.

2. Semiconductor and electronics industry:

In semiconductor manufacturing processes, tantalum crucibles can be used as containers for carrying and heating raw materials in processes such as chemical vapor deposition (CVD) and physical vapor deposition (PVD). For example, in the manufacturing process of OLED, it is necessary to heat the crucible under high vacuum to evaporate and attach to the substrate surface, and tantalum crucible can be used because of its good performance.

Anode materials used for the manufacture of electronic components, such as tantalum capacitors, need to be treated at high temperature. The tantalum crucible can be used as a container for carrying anode materials to ensure the stability and purity of the material during high temperature treatment.

3. Metal smelting and casting field:

Tantalum crucible can withstand high temperature and metal melt erosion, and can be used for smelting various rare metals, precious metals and superalloys. For example, tantalum crucibles are commonly used containers for smelting refractory metals such as tungsten, molybdenum, niobium, and zirconium and titanium alloys.

In the casting process, tantalum crucible can be used to pour the molten metal liquid into the mold, especially for the production of metal castings with high purity requirements and strict control of impurity content.

4. High-temperature sintering field:

In the high-temperature sintering process in the powder metallurgy industry, the tantalum crucible can be used to place materials such as metal powder or ceramic powder for sintering in the high-temperature furnace to prepare high-performance metal or ceramic materials. For example, tantalum crucibles are used when preparing materials such as carbide carbide and high-temperature ceramics.

For some materials that need to be sintering under high temperature, high vacuum or special atmosphere, such as the bearing plate of tantalum niobbium electrolytic capacitor anode.

5. Aerospace field:

The performance requirement of materials is extremely high in the aerospace field.
