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.

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.

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.

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:

Tungsten heavy Alloy with High Specific Gravity is an alloy with tungsten as the main content and other elements added, which can form various classifications according to the added elements.

Medical Tungsten Alloy Shield is an ideal choice for manufacturing medical radiation shields. With the improvement of people's living levels and the continuous development of science and technology, the concept of green and healthy life has been deeply rooted in people's hearts. Traditional radiation shielding materials have been difficult to meet people's growing needs for life and health. It is very important to find a safe and reliable protective material for people's life and health. Medical tungsten alloy shield has the characteristics of high density, strong radiation shielding and environmental protection, which just meet the needs of people pursuing healthy life, so it is widely used in many aspects of medical domain.

Cobalt (Co) is vital to the human body and plays an important role in various biological processes. However, excessive intake of Co compounds has been shown to adversely affect the health of the skin, lungs, and thyroid. Therefore, it is necessary to design a fast, accurate and cost-effective sensor to detect the Co content in drinking water.

Tungsten trioxide (WO3) has been widely applied ain polymorphism, electrochromism and gas phase change. WO3 is also a promising material that can be used for field emission, solar energy and storage.Transition metal oxides (TMO) are used in supercapacitors to increase capacitance and energy density through pseudocapacitance or Faraday mechanism. WO3 is also an excellent transition metal oxide. Although WO3 is a   promising material for supercapacitor electrodes. It lacks chemical stability, yielding low life cycle values.

Ammonia (NH3) is a gas present in the entire atmosphere in relatively small concentrations (1–5 ppb) and is mainly emitted by human activities. Ammonia causes negative effects to living beings. Therefore, it has been suggested 25 ppm as an allowed exposure level of ammonia concentration. Thus, it is important to find a sensing material for ammonia sensing at room temperature.

Tungsten Trioxide (WO₃) is a kind of relatively stable tungsten oxide. Because of its electrochromic, photochromic, gas-chromic and other special properties, WO₃ smart glass is a product that meets the needs of modernization. How to apply Tungsten Trioxide to smart glass?
