Tungsten Trioxide（WO3）is an electrochromic semiconductor material with early discovery, deep study and wide application. It has good chemical stability, no toxicity, great difference in optical properties between coloring and fading, and long cycle life, so it has been widely used in the field of energy conservation.

With the continuous progress of science and technology, people's quality of life has been greatly improved, but must the development of science and technology bring a good side to mankind? Not necessarily, but also has negative effects. For example, people pay more attention to pollution, which is the “sequela” left by the treatment technology failing to keep up with the development of science and technology. In order to reduce the pollution level, relevant researchers are committed to finding an efficient and environmental protection material, and Tungsten Trioxide (WO3) can be used as this material.

In recent years, Tungsten Trioxide (WO3) has been favored by researchers for its many special properties. For example, when WO3 is used as a photocatalyst, it can be used for air purification, self-cleaning, inorganic and organic synthesis, hydrogen production by photolysis of water and control of oxygen and heavy metals pollution.That's all thank s to its photocatalytic property.

Strict control of high density tungsten alloy production technology has a vital impact on the strength, brittleness, impact toughness, hardness and corrosion resistance of products. There is an efficient and stable high density tungsten alloy production technology comprises the following steps:
