Tantalum joining

Joining Tantalum can be joined by riveting, brazing and welding however, due to the good properties of welded joints the former techniques are seldom used. 

Use Brazes to join molybdenum, tungsten, tantalum, and niobium parts, especially electronic components, corrosion and abrasion-resistant parts, cutting tools, refractory cermets. 

A schematic diagram of the power generation test apparatus is shown in Figure 2. The emitter, which was a disc with a diameter of 16 mm and a thickness of 5 mm was joined using ruthenium-molybdenum braze to a support made of tantalum, and was placed facing the molybdenum collector at a distance of 400 im. The emitter was heated to 1400 1900 K by electron bombardment Then the collector was cooled by radiative cooling to about 1000 K.
