Characteristics and application fields of tantalum rod

Date:2021-04-18View:3005

Tantalum also has excellent chemical properties and high corrosion resistance. It has no reaction to hydrochloric acid, concentrated nitric acid and “aqua regia” under both cold and hot conditions. When tantalum is immersed in sulfuric acid at 200 ℃ 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 show that tantalum rod does not work on alkali solution, chlorine, bromine, dilute sulfuric acid and many other reagents under normal conditions, but only reacts under the action of hydrofluoric acid and hot concentrated sulfuric acid. Such a situation is relatively rare in metals.

Tantalum has a wide range of applications due to its characteristics. In the equipment for preparing various inorganic acids, tantalum can be used to replace stainless steel, and its service life can be dozens of times longer than that of stainless steel. In addition, in chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be undertaken by platinum, which greatly reduces the cost.

In addition, tantalum is also an important element for refining super strong steel, corrosion-resistant steel and heat-resistant steel alloys, which can provide special materials necessary for the development of space technology such as rockets, spacecraft 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 great 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 the turning tool made of it can cut many hard alloys at high speed; All kinds of drill bits made of it can replace the hardest alloy or diamond. Therefore, tantalum is also considered as a “vitamin” in smelting.
