The light response of bismuth tungstate is good, but in practice, it usually needs modification. Some researchers have used graphite loaded bismuth tungstate to make composite materials. The preparation process is as follows:

Bismuth tungstate is a layered structure, and bismuth tungstate has a photocatalytic performance under visible light. It can photolysis and photodegradation of organic pollutants in visible light. Therefore, bismuth tungstate has a good application prospect in many related fields.

Photocatalysis is a technology that uses the energy of natural light to convert into chemical reaction and produces catalytic technology to decompose organic substances which are harmful to the human body and the environment, and will not cause the waste of resources and the formation of additional pollution. Bismuth tungstate is a typical representative of new photocatalysis. The research is focused on the development of a new type of Bi₂WO₆ based composite photocatalyst. Modification are the effective means to improve the photocatalytic level of bismuth tungstate.

How to reduce all kinds of radiation intensity, effectively protect the environment and protect human health has been urgently mentioned on the agenda. Chinese researchers have developed a new type of tungsten radiation protective clothing, which reduces the cost through technology. The implementation of the process is as follows:

Energy conservation is a problem that must be considered in the sustainable development of every country's economy. In the energy consumption of many countries, building energy consumption accounts for about 30 ~ 40% of the national energy consumption, while the energy consumed through glass doors and windows accounts for more than 50% of the energy consumption of the building. If the transmission of near infrared light is reduced, the heat shielding effect will be greatly improved. Transparent heat insulation coating and transparent heat insulation film have bright prospects for economic, convenient use and good insulation effect.

The modification methods of bismuth tungstate can be used in various ways. Researchers have provided a method for the preparation of bismuth / polyaniline composite photocatalyst with a simple process and excellent product performance. It is said that the composite photocatalyst has a good effect on the treatment of methylene blue in sewage.

With the rapid development of science and technology, many new desulphurization technologies have been developed. Catalytic oxidation desulfurization is a new desulfurization technology. Catalytic oxidation desulfurization has a wide range of applications, the process does not consume hydrogen, and is easy to implement. The catalyst plays a very important role.

The traditional coarse grain tungsten carbide powder is produced by using the coarse tungsten powder reduced by Li⁺ or Na⁺, and rolling ball milling in the common carburizing device, and then heating in the ordinary carbon tube for high temperature (1800 to 2000 degrees C) for a long time carbonization.

Adding a certain amount of rare earth elements in tungsten can change the properties of tungsten wire, such as adding cerium or thorium in tungsten can improve the electronic emission and ablative ability of the tungsten, and improve the processing properties of tungsten. The tungsten alloy wire and products produced by these characteristics are mainly used for electron tube hot wire, argon arc welding electrode and pulse tube heating wire.

The key of photocatalytic technology is the photocatalyst. Bismuth tungstate as a new type of bismuth series of new photocatalyst. It is a multicomponent compound with layered structure. The lamellar formation is formed by the common angle of the WO₆ eight sides, and a layer of [Bi₂O₂]²⁺ is distributed between layers. Bi₂WO₆ is a typical bismuth series photocatalyst. It exhibits excellent visible light photocatalytic activity in environmental pollution control and solar energy conversion. Bi2WO6 has high catalytic activity under visible light irradiation, which can cleavage aquatic O₂ and degrade organic matter.
