Large-scale integrated circuits often use tungsten target for vacuum sputtering, especially large-size tungsten target. In the current semiconductor field, large-size tungsten target has a diameter of 300 mm-450 mm and a thickness of 6 mm-15 mm. However, with the development of semiconductor industry, tungsten target of this size can not meet the industrial needs.

According to experts, in the near future, tungsten oxide electrochromic glass can easily achieve warm winter and cool summer! It is said that this is a black technology achievement! Just press the power switch lightly to make the glass "discolor" instantly, from transparent to dark blue. Ordinary glass does not have thermal insulation, and this black technology can make the glass block most of the sunlight in the hot summer, reduce the indoor temperature, thus reducing air conditioning costs and saving energy. Some experts also said that this kind of glass has a certain thermal insulation effect. Moreover, unlike other materials, it only consumes power during the state transition.

Sputtering is one of the main technologies for preparing thin film materials. Atomics emitted by high-speed moving ions bombarding the target accumulate on the surface of the substrate to form a coating. The bombarded solid is the raw material for deposition of thin film by sputtering, which is called sputtering target.

Shizhuyuan Tungsten-Molybdenum-Bismuth Polymetallic Ore in Hunan Province, China belongs to a large SKARN-TYPE polymetallic ore body. There are many valuable minerals in the ore with complex distribution relationship and low grade. It is difficult to separate more than 20 kinds of ore, such as tungsten, molybdenum, bismuth, iron and fluorite. How to effectively separate and comprehensively recover valuable minerals has become a hot academic topic for scholars at home and abroad.

Tungsten trioxide is an important inorganic photochromic material, which has wide application prospects in large screen display and high density information storage. Compared with organic photochromic materials, WO₃ has good stability and low cost, but its photochromic efficiency is poor. In order to improve the discoloration efficiency of this kind of inorganic materials, scholars at home and abroad have proposed various solutions and achieved many results.

The chemical properties of tungsten and molybdenum are similar, and they are often associated with each other in nature. In the current tungsten smelting process, the separation of tungsten and molybdenum has become a very important process, among which the selective precipitation method is the most concerned.

The crystals of CaWO₄, PbWO₄, NaBi (WO₄) ₂ and CaMoO₄ with Scheelite structure (ABO₄) are better scintillators or X-ray emitters. The results show that the molybdate and tungstate with Scheelite structure belong to tetragonal system, and their grains are tetragonal, biconical or plate-like. They are important photoelectric functional materials, scintillating materials and fluorescent materials.

Dropping is a consumable item in fishing, including weights on hooks for bottom sinking, weights placed in false baits, and more directly processed into false fishes, such as Luya.

Among many photocatalytic materials, bismuth tungstate is a kind of visible-light photocatalyst with good photocatalytic activity. Bi₂WO₆ is a typical semiconductor material. Electrons are stimulated by light and leave corresponding holes to form electron-hole pairs. These photogenerated electron-hole pairs have strong redox ability. They are easy to react with organic substances and polymer, and they respond well to visible light because of their narrow band gap.

Since the discovery of platinum-like catalytic performance by American scientists in the last century, tungsten carbide has been found to have high catalytic or catalytic activity in hydrocarbon reforming, decomposition, hydrogenation, isomerization, electrochemical oxidation of hydrogen and alcohols, and electrochemical reduction of oxygen.
