Tantalum rod characteristics and application fields

Tantalum rod characteristics and application fields

Tantalum also has excellent chemical properties and is extremely corrosion-resistant. No matter under cold or hot conditions, it has no reaction to hydrochloric acid, concentrated nitric acid and "aqua regia". When tantalum is soaked in sulfuric acid at 200°C for one year, the surface layer is only damaged by 0.006 mm.

Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible. Experiments have proved that tantalum rods are insensitive to alkali solution, chlorine gas, bromine water, dilute sulfuric acid and many other chemicals under normal conditions. It only reacts under the action of hydrofluoric acid and hot concentrated sulfuric acid. Such situations are relatively rare in metals.

The characteristics of tantalum make its application fields very broad. In equipment for preparing various inorganic acids, tantalum can be used to replace stainless steel, and its service life can be extended dozens of times compared to stainless steel. In addition, in the chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be performed by the precious metal platinum, greatly reducing the cost.

In addition, tantalum is also an important element in refining super-strong steel, corrosion-resistant steel and heat-resistant steel alloys, and can provide special materials necessary for the development of space technologies such as rockets, spacecrafts, and jet aircraft. Non-magnetic alloys made of tantalum and tungsten are widely used in the electrical industry, especially tantalum carbide, which is composed of tantalum and carbon. It has extremely hardness and is comparable to diamond even under high conditions.

Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible. Turning tools made of it can cut many hard alloys at high speed; various drill bits made of it can replace The hardest alloy or diamond. Therefore, tantalum is also considered a "vitamin" in smelting.
