Tantalum Powder Preparation Methods. Tantalum powder is powdered metal tantalum, dark gray, or silver-gray, which is an important raw material for the preparation of capacitors and tantalum materials. In this article, let's take a deeper look at the tantalum powder preparation methods.Before going any further, let's figure out the types of tantalum powder.
Rhenium powder is used, inter alia, in the medical industry. It is an additive in the super alloys used in production of components that require resistance to high temperatures, such as aircraft engine parts, gas turbines, filaments and heat shields. Intensive work is also underway on the use of rhenium as a component of materials for 3D printers.
Tantalum Tantalum is also famous for its resistance to corrosion by acids. In fact, below 150°C, tantalum is almost completely immune to corrosion by aqua regia. Due to its resistance to attack by body fluids, tantalum provides excellent material for medical devices.

Another major use of tantalum is for electronic components and due to its absorption properties; it is an excellent getter of residual gasses in evacuation tubes. Tantalum can be alloyed with tungsten, niobium and rhenium; however these binary alloys exhibit a lowering of temperature sensitivity of flow stress.
The present invention provides a method for preparing a rhenium-tantalum alloy with improved strength and ductility characteristics. The method includes mixing powders of rhenium and tantalum with a weight ration of approximately 97% rhenium to approximately 3% tantalum. The powdered blend is then compressed to a green state. The green compress of rhenium and tantalum is then sintered such ...
