Why is tantalum so rare?
Tantalum has excellent chemical properties and is extremely resistant to corrosion. It does not react to hydrochloric acid, concentrated nitric acid, or “aqua regia” under either cold or hot conditions. When tantalum is immersed in sulfuric acid at 200°C for one year, the surface layer is only damaged by 0.006 mm.
What is tantalum is used for?
Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible experiments have proved that tantalum rod does not react to an alkaline solution, chlorine gas, bromine water, dilute sulfuric acid and many other agents under normal conditions, but only reacts to hydrofluoric acid and hot concentrated sulfuric acid. This is a relatively rare occurrence among metals.
What devices use tantalum?
The properties of tantalum make it suitable for a wide range of applications. In equipment for the production of various inorganic acids, tantalum can be used as a replacement for stainless steel, and its life can be increased by dozens of times compared to stainless steel. In addition, in the chemical, electronic and electrical industries, tantalum can replace the tasks that used to be undertaken by the precious metal platinum, making the costs required much lower.
In addition, tantalum is also an important element in the refining of super-strength steel, corrosion-resistant steel, and heat-resistant steel alloys, and can provide special materials necessary for the development of rockets, spacecraft, jet aircraft, and other space technologies.
Non-magnetic alloys made of tantalum and tungsten are widely used in the electrical industry, especially tantalum carbide composed of tantalum and carbon, which has great hardness, even under high conditions, and gold steel stone is not comparable.
Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible 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 gold steel stone. Therefore, tantalum is also considered to be the “vitamin” in smelting.
