Tungsten has many advantages, such as high melting point, high density, high strength, high hardness, low thermal expansion coefficient, excellent corrosion resistance and good processing performance, so it is widely used in aviation, aerospace, electronics, chemical industry, military weapons and other fields.

Silver tungstate material is a kind of important metal tungstate material. It has unique crystal structure and stable physical and chemical properties. Therefore, it can be used as a good luminescent matrix material, photocatalytic material and inorganic anti-bacterial material. It has bright application prospects in scintillator preparation, photocatalysis, medical environmental protection and other fields.

Tungsten has been widely used because of its high melting point (3410 ℃) and excellent physical and chemical properties, such as rocket and aircraft engine parts, gas rudder control components, rocket's forebody, contact plug, radiator and so on.

At present, energy consumption and environmental problems have become the focus of attention all over the world. As the highest energy density, clean and efficient renewable energy, hydrogen is the most potential new energy in the 21st century. It is expected to replace fossil energy in people's production and life in the near future.
