Characteristics and application areas of pure tantalum rods
Many friends are still unfamiliar with the material pure tantalum rods. In fact, the melting point of tantalum rod is 2996 degrees Celsius and the density is 16.68 g/cm. However, due to its high temperature resistance, corrosion resistance, cold working and good welding performance, tantalum is widely used in electronics, semiconductors, chemicals, machinery, aerospace, medical, etc. It has been widely used in military industry and other industries.
Pure tantalum rods have excellent chemical properties. They have extremely high corrosion resistance. They are unresponsive to hydrochloric acid, concentrated nitric acid and "aqua regia" under both cold and hot conditions. Put tantalum into a furnace at 200 degrees Celsius. After being soaked in sulfuric acid for one year, the surface layer was only damaged by 0.006 mm. Tungsten plates, tungsten rods, molybdenum plates, tungsten tubes, molybdenum tubes, and tungsten crucible experiments have proven that pure tantalum rods have no effect on alkali solutions, chlorine water, dilute sulfuric acid, and many other chemicals at room temperature. They only react with hydrogen fluoride. It reacts under the action of acid and hot concentrated sulfuric acid. This situation is actually relatively rare among metals.
The characteristics of pure tantalum rods make it widely used in equipment for preparing various inorganic acids. It can be used to replace stainless steel, and its service life can be increased dozens of times compared with stainless steel. In addition, it is widely used in chemical industry, electronics, In electrical and other industries, tantalum can replace tasks previously performed by the precious metal platinum, greatly reducing the cost.
In addition, pure tantalum rods are also an important element in refining super-strong steel, corrosion-resistant steel and heat-resistant steel alloys. They can provide special materials necessary for the development of rockets, spacecrafts, jet aircraft and other space technologies. Non-magnetic rods made of tantalum and tungsten Alloys 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.
