The doped tungsten wire is the wire that dopes certain amount of potassium and silicon into pure tungsten powder. It will not only increase the color temperature, luminous efficiency and life time of wire, but also has well anti sag propery, it can be used as special lamp filament with high working temperature such as halogen lamp. Provided that some alloy elements such as cobalt are added into the doped wire, the wire will have high strength and shock resistance. The wire is generally used in lighting system in vibration environment, lamps for various vehicles (motorcycles, automobiles, trains, airplanes, etc) as well as special light bulbs for military purposes, heating wires for aeroengine, etc.

Tungsten is used in the production of numerous end use items. It is widely used for high temperature applications such as filaments in light bulbs, cathodes in high power lamps, and rocket nozzles in space crafts. Tungsten is also used in the manufacture of superalloys and catalysts. In addition, its considerable applications in industry as a refractory metal owing to its outstanding hardness and wear resistance in the form of tungsten carbide are well known.

Tungsten and its alloys are the major materials applied in fusion reactors owing to their high melting point, high thermal conductivity, high strength at elevated temperatures, low sputtering yield in radiation environment.

Ammonium metatungstate (AMT, (NH4)6H2W12O40·yH2O) is a polycondensation product of solutions of ammonium tungstate. The applications of it include high distectic point metal, extra fine alloy, petrochemical catalyzer and nuclear energy, space flight, casting titanium, etc.

Titanium dioxide (TiO2) photocatalysis using sunlight as an irradiation source is a feasible technique to degrade pollutants in air. Although TiO2 possesses enticing properties such as chemical stability, strong oxidizing power, photo-resistance, availability, and low cost, its photocatalytic activity remains insufficient for large-scale applications.

WC-Co cemented carbides are widely applied in industry which include mining, grinding and metal cutting tools.  Its high hardness and toughness give its widely industrial applications. The microstructural scale is a major to influence its mechanical properties. The hardness can be enhanced by with smaller carbide grain size. The common grain size of WC-Co ranges within l-10 pm.

Tungsten carbide (WC) has been widely applied as integral composition of hardmetal, or cemented carbide. Cemented carbides are composite materials consisting of a hard phase (WC) and a metal, usually Co, which binds the WC grains. The composition of the material (amount of Co) mostly influences their mechanical properties. The greater the Co content the tougher and softer the material is. Hardmetal is used for cutting, drilling and wear resistant pieces.

Tungsten copper is a material with high electricity conductivity, when using for resistance welding, the material is bonded with copper hand.

In recent years, ultrafine tungsten powders have gained attention owing to their excellent characteristics. They have been added to hard metals and alloys with superior hardness and wear resistance.

As the fossil fuels brings about global warming and climate change, find a substitute source of clean energy such as wind energy, hydrogen energy, and solar energy has become critical. Photoelectrochemical (PEC) water-splitting technology is one of the most considerable technologies to synthesis H₂ gas as a clean energy. Titanium dioxide (TiO₂) has caught a lot attention as an effectual photoelectrode in PEC water-splitting for H₂ production owing to its unique and promising functional properties, such as high photocatalytic activity, long term photo-stability, superior oxidation ability, inertness to chemical environment, as well as low cost.
