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?

As industrial teeth, tungsten is an important raw material in machining and manufacturing. Tungsten-based cemented carbide tools have a series of excellent properties, such as high strength, good toughness, high temperature resistance, wear resistance and corrosion resistance. Even at 500 degrees Celsius or even 1000 degrees Celsius, the hardness basically keeps a high level. Tungsten Cemented Carbide Cutting Blade, which promotes the rapid development of high-speed and high-efficiency cutting technology.

Tungsten Alloy Extrusion Die is a technology for forming parts by extrusion die in the process of high-strength extrusion.

Tungsten alloy shield is widely used in medical industry and nuclear industry because of its excellent radiation shielding ability. Despite the development of science and technology and the continuous improvement of people's modern living standards, it is inevitable that some radiation problems will be encountered in life, causing people to pay special attention to the safety and protection of radiation.

Tungsten Alloy Automobile Counterweight can adjust the center of gravity of chassis when it is used in automobile, and make the center of gravity close to the ground, so that the automobile body can resist the ascending airflow of air resistance and keep running smoothly during high-speed driving. This greatly improves the maneuverability of the automobile and the sensitivity of the control mechanism.

Tungsten Trioxide (WO₃), as an N-type semiconductor material with good mechanical stability, photoelectric effect and electrochromic characteristics, is favored in the field of energy storage and used by researchers at home and abroad to replace cobalt in lithium-ion batteries.

Tungsten Trioxide ceramics are a metal cermet, which means that people add a certain proportion of Tungsten Trioxide into the clay for making ceramics to make ceramics with the advantages of high temperature resistance and non-friability. Compared with traditional ceramics, it not only retains the original advantages, but also increases the high temperature resistance, chemical corrosion resistance, good thermal conductivity and other advantages of tungsten.
