Tungsten Trioxide (WO3), as a material with high gas sensitivity, high sensitivity and short response time, can be used as a gas sensor, and has been widely used in life and industry.

In recent years, as a highly sensitive material, Tungsten Trioxide (WO3) has many advantages, such as short response and recovery time, appropriate response temperature, easy measurement and control, and low price. It can be used in the military and national defense fields, and has attracted people's concern.That's all thanks to its gas sensing property.

Tungsten Trioxide (WO3) thin film is a kind of functional material with large transmittance change, good reversibility, low relative price, long life, non-toxicity and environmental protection, and it is the earliest and most widely used electrochromic material. The application of this electrochromic material is hidden in our daily life. For example, it can be made into smart windows, which can save energy, dim light, control heat load and other functions. Therefore, in order to study the properties of Tungsten Trioxide thin films, researchers have continuously improved their preparation methods, such as preparing WO3 thin films by electrodeposition, which has become a research hotspot in recent years. The following is a general procedure for preparing Tungsten Trioxide thin films by electrodeposition method.

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.
