Tantalum is a high-density hard metal with high ductility, thermal and electrical conductivity. Tantalum is a refractory metal, often used as a secondary component of alloys; Low chemical activity, suitable to replace platinum as a material for experimental equipment. Tantalum can resist acid corrosion, and it can even resist aqua regia erosion below 150 °C.
Tantalum application: At present, the main application of tantalum is tantalum capacitor, which is useful in electronic equipment such as mobile phones, DVD players, electronic game consoles and computers. The largest applications of tantalum are electronic components made of tantalum powder, mainly capacitors and high-power resistors. Tantalum can be used to make a variety of malleable alloys with high melting points. These alloys are used as materials for superhard metalworking tools, as well as superalloys for jet engines, chemical experiments, nuclear reactors, and missiles. Tantalum is widely used to make surgical tools and implants because it resists the erosion of biological fluids and does not irritate tissue. Tantalum resists almost all acids except hydrofluoric acid and hot sulfuric acid. Therefore, tantalum can be used as a material for chemical reaction vessels and corrosive liquid conduits.
Tantalum has a high melting point and can resist oxidation, so it can be used as a material for vacuum furnace components. Tantalum is highly malleable and can be stretched into silk. These tantalum wires are used to vaporize various metals, such as aluminum. Hastelloy is a kind of nickel-based corrosion resistant alloy, mainly divided into nickel-chromium alloy and nickel-chromium molybdenum alloy two categories. It has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields. Hastelloy plates are suitable for various chemical industries containing oxidizing and reducing media. The high content of molybdenum and chromium make the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy tube is a nickel-chromium-molybdenum alloy containing tungsten, which is one of the only several materials resistant to the corrosion of humid chlorine gas, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high concentrations of chloride salt solutions such as ferric chloride and copper chloride, and extremely low silicon carbon content, which is considered to be a universal corrosion resistant alloy.
