With the upcoming construction of the International Thermonuclear Experimental Reactor (ITER), the study of plasma-facing materials (PFM) used in ITER has become a popular and frontier research direction, as it is a key component of fusion reactor.

For many years, tungsten alloy has been the best choice for engineers and doctors regarding nuclear medicine. One key reason for this is the high density of tungsten alloy. In fact, it is more than 60% denser than lead, providing superior attenuation characteristics for x-ray and gamma radiation.

Tungsten alloy has been widely used in hunting guns.High density, great hardness and resistance to high temperature make tungsten to be one of the most sought-after materials for shotgun pellets in shooting history.

Optical absorption results revealed the WOx/CsyWO3 heterostructured composite exhibits a strong absorption tail in the Vis and NIR regions which could have important implications for its photoactivity. It can be used as photocatalyst. The photocatalytic performance of synthesized samples with different Cs/W molar ratios was evaluated by the photodegradation of RhB in aqueous solution under simulated solar light irradiation.

Tungsten alloy counterweight is a F1 specific tuning option and is now becoming the most popular material for balancing race cars. Tungsten heavy alloy is the best material to be used as counterweight which can be used in motor sport, because it has the good properties: high density with small volume, high temperature resistance, non-toxic and environmentally.

Tungsten alloy submarine counterweight can diminish the extent of stabilizer with its high thickness so it can add to the conveyance of weight and enhance affectability of control system. 

In the tungsten-copper alloy, the high melting point tungsten forms a refractory skeleton, which makes the material resistant to arcing, abrasion and high temperature, while the low melting point copper (Cu) has excellent electrical conductivity, thermal conductivity and good plasticity. Therefore, tungsten-copper alloy is widely used as an electrical contact material for high-voltage and ultra-high-voltage electrical switches.

With the shortage of freshwater resources, the environment-friendly water-saving technology using seawater as circulating cooling water has a wide application demand in high water-consuming industries such as electric power and chemical industry. However, the salt content of seawater is high and its composition is complex, which is more corrosive than that of fresh water. Therefore, the biggest technical difficulty in using seawater as circulating cooling water is to solve the corrosion problem of seawater.

Hollow sphere is a kind of material with special structure from nanometer to micrometer in size. Because of its low density, large specific surface area, good stability and surface permeability, these materials have important applications in chemistry, biology and materials science.

Tungsten disulfide is a gray-black hexagonal lattice-like material similar to graphite. Each layer is composed of two layers of sulfur atoms and one layer of tungsten atoms connected by the number of 2:1. Among them, sulfur and tungsten atoms are connected by strong covalent bonds. Sulfur atoms between layers are connected by van der Waals forces. The special crystal structure also makes tungsten disulfide more excellent than molybdenum disulfide lubricating oil additive of the same kind. Tungsten disulfide performs better in extreme pressure, wear and friction reduction, heat and oxidation resistance, etc.
