Refractory metal materials mainly refer to tungsten, molybdenum, tantalum, niobium, rhenium, and vanadium, all of which are materials with a melting point above 2000 degrees Celsius. Refractory metal materials and their alloys have the characteristics of high melting point, high strength under a high-temperature environment, strong corrosion resistance to liquid metal and processing plasticity. Refractory […]
The tolerance of tantalum to interstitial elements and reasonable elastic modulus make it an attractive base element of the alloy. Tantalum is also easy to achieve the inert gas tungsten arc welding (GTA), so it is suitable for the manufacture of various chemical equipment to give play to its corrosion resistance, such as various heat exchangers, […]
Tantalum occurs in columbium ores. As the demand for columbium increases, increasing amounts of tantalum concentrates become available. After a difficult and complex separation and reduction process, both metals are obtained in the form of powder. The powder is pressed in dies to form bars which are vacuum sintered by passing high currents through them […]
