Scientists at a British university are experimenting with tungsten in a world-class new facility to help develop a new fusion reactor, ITER. ITER refers to the International Thermonuclear Fusion Experimental Reactor, which is known as the "artificial solar" project. Many countries involved in the research believe that if the "artificial sun" can be realized, it will produce almost unlimited clean energy, which is inexpensive and incalculable.

Tungsten disulfide is a fine gray crystalline or powder with metallic luster. It belongs to hexagonal crystal system. It has semiconductor and diamagnetic properties, layered structure, easy dissociation, and lubricating properties similar to graphite. It is mainly used as lubricant. Its performance is better than molybdenum disulfide. Its friction coefficient is lower and its compressive strength is higher.

Tin dioxide is an n-type semiconductor material with good chemical stability and optical anisotropy. It is widely used in gas-sensitive materials, photoelectric materials, lithium-ion battery materials and other fields. By doping, tin dioxide can become semiconductor or conductor, improve its conductivity and spectral selectivity, and expand its application range.

Transition metal oxides can be used in various fields. Molybdenum oxide and tungsten oxide, as two important transition metal oxides, have attracted the attention of scholars and experts in the fields of photocatalysis and gas sensors for a long time. In the past few years, it has been found that the properties of binary molybdenum tungsten oxide (MoxW1-xO3) materials can be greatly improved due to the "synergistic effect" of the two elements. Therefore, by changing the composition and structure of materials, we can make this "synergistic effect" play a stronger role.
