At present, some new tungstate photocatalytic materials with visible light effect have been discovered by researchers. Semiconductor materials such as tungstate have good application prospects due to their unique structure and physicochemical properties, such as magnetic devices, scintillators, corrosion inhibitors and catalysts, which have become a research hotspot in recent years. For example, the catalytic material Bi₂WO₆ (band gap is only about 2.8eV), which is faster than the visible light response photocatalysis of TIO₂, can mineralize harmful substances such as chloroform and acetaldehyde under visible light, and degrade them into CO₂.

In recent years, the research of two-dimensional layered materials has attracted the attention of scientists, especially the rapidly developing graphene nanomaterials, which have the characteristics of high strength, excellent conductivity and thermal conductivity, and are widely used in the field of sensors. Graphene is known as the king of new materials. However, graphene is a two-dimensional material with zero band gap and can not be used as channel layer of transistors, which limits its further application in nano-electronic devices and photoelectric conversion.

Because of its excellent properties such as high hardness, high red hardness, high compressive strength, high wear resistance and good corrosion resistance, superfine tungsten carbide powder is known as "industrial teeth" and widely used in almost all sectors of the national economy and various fields of modern technology. As the main material of cemented carbide, tungsten carbide has been devoted to improving its contradictory properties of hardness and toughness.

Because of its high melting point and high high temperature mechanical properties, tungsten metal is widely used in high temperature components, lighting, national defense and other fields. Besides, tungsten metal has the advantages of low thermal expansion coefficient and anti-sputtering. It is the most promising candidate wall material for fusion reactor. However, tungsten has some shortcomings, such as low temperature brittleness and recrystallization brittleness, which lead to brittleness and difficult to process and shape, and affect its application.
