Electronic field
Tungsten has strong plasticity, low evaporation rate, high melting point, and strong electron emission ability, so it is widely used in the electronics and power supply industry. For example, tungsten filament has high luminous efficiency and long service life and is often used to make various bulb filaments, such as incandescent lamps, iodine tungsten lamps, etc. In addition, tungsten filament can also be used to make direct-heated cathodes and grids of electronic oscillator tubes and cathode heaters in various electronic instruments.
Chemical field
Tungsten compounds are often used to produce certain types of paints, pigments, inks, lubricants and catalysts. For example, sodium tungstate is often used in the manufacture of metallic tungsten, tungstic acid and tungstates, as well as dyes, pigments, inks, electroplating, etc.; tungstic acid is often used as a mordant and dye in the textile industry, and as a catalyst for the preparation of high-octane gasoline in the chemical industry; tungsten disulfide is often used in organic synthesis, such as in the preparation of synthetic gasoline as a solid lubricant and catalyst; bronze tungsten oxide is used in painting.
Medical field
Tungsten alloys are very suitable for medical fields such as X-ray and radiation protection due to their high hardness and density. Common tungsten alloy medical products include X-ray anodes, anti-scatter plates, radioactive containers, and syringe shielding containers.
Military field
Tungsten products have been used to replace lead and depleted uranium materials to manufacture bullet warheads due to their non-toxic and environmentally friendly properties, to reduce the pollution of military materials to the ecological environment. In addition, due to its strong hardness and good high-temperature resistance, tungsten can make the combat performance of the prepared military products more superior. The main tungsten products used in the military are: tungsten alloy bullets, and kinetic energy armor-piercing bullets.
In addition to the above fields, tungsten can also be used in aerospace, navigation, atomic energy, shipbuilding, the automotive industry, and other fields.
