Tantalum particles refer to small particles made of tantalum metal. Tantalum is a rare, hard, and dense metallic element with the atomic number 73. It is typically found in minerals such as tantalite, columbite, and coltan. Tantalum has a very high melting point, exceptional corrosion resistance, and is biocompatible, making it suitable for use in a variety of applications. Tantalum metal particles are used in the manufacturing of electronic components, such as capacitors, as well as in the production of alloys and superalloys used in the aerospace and medical industries. Tantalum metal particles can be produced through various methods, such as powder metallurgy and chemical vapor deposition.
Tantalum Grade is as follows:
1) R05200, unalloyed tantalum, electron-beam furnace or vacuum-arc melt, or both.
2) R05400, unalloyed tantalum, powder-metallurgy consolidation.
3) R05255, tantalum alloy, 90 % tantalum 10 % tungsten, electron-beam furnace or vacuum-arc melt, or both.
4) R05252, tantalum alloy, 97.5 % tantalum 2.5 % tungsten, electron-beam furnace or vacuum-arc melt, or both.
5) R05240 tantalum alloy, 60 % tantalum 40 % columbium, electron-beam furnace or vacuum-arc melt, or both.
