W50 tungsten copper rod is composed of 50% W and 50% Cu, which not only has high density (11.85g/cm3), high hardness (≥HB115), high strength, but also has good conductivity (%54IACS), softening temperature is ≥900℃.

The crystal structure of tungsten trioxide belongs to ReO₃ type and its band gap is about 2.8eV. Tungsten trioxide has unique physical and chemical properties. It has wide application prospects in gas sensing, electrochemistry, electrochromic, photocatalysis and other fields.

When using traditional WC-17Co thermal spraying powder, its crack resistance is better than that of WC-12Co spraying powder because of its high cobalt content, but its hardness is relatively low. When the hardness of the coating is increased by adjusting, the toughness of the coating decreases obviously. How to achieve a balance between toughness and hardness? Therefore, some scholars have found a way to synthesize tungsten carbide coating materials.

At present, the recycling of tungsten resources mainly focuses on tungsten-containing alloy waste and tungsten-containing catalyst waste. Ammonium paratungstate waste contains a lot of sediment, and its acid-base solubility is poor. The chemical recovery method is used to recover and utilize the environment, which is polluted greatly, the equipment is corroded seriously and the cost is high. Therefore, although there are many studies on ammonium paratungstate waste recycling, most of them are still in the laboratory pilot study stage. Recently, some scholars have published a method to recover tungsten and tin from waste. The process includes these steps:

Ammonium paratungstate is an important raw material for preparing tungsten products. At present, the main process of industrial production of tungsten powder is calcining ammonium paratungstate into blue tungsten, then reducing in hydrogen to prepare tungsten powder. The particle size of tungsten powder prepared by this method is mostly between 2 and 4 microns, which has become the main raw material for preparing tungsten alloys in the fields of military industry and medical devices.

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, larger tungsten targets are needed.

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.
