Metastable intermolecular composite (MIC) materials is an intimate mixture of two or more compounds of which at least two are exothermically reactive. However, conventional thermites have a significantly lower reactive power. In contrast, MIC materials, while retaining the high energy density, can have a significantly higher reactive power than conventional thermites.

The most accepted recycling of tungsten scraps are hydrometallurgy or hydrothermal treatment methods. The common recycling process of tungsten scraps to produce ammonium paratungstate (APT) is carried out by the oxidation, milling, fusion, dissolution and extraction processes. Among which, oxidation is the key factor to the recovery rate of tungsten scraps. 

Spherical tungsten powder is used as a raw material in industries such as tungsten and tungsten alloy 3D printing, porous materials, and high-density powder spraying, and its preparation methods have attracted attention. So, what are the 6 preparation methods for spherical tungsten powder?

Tungsten carbide-based cemented carbide is widely used in cemented carbide, and high-quality tungsten carbide powder is the basis for preparing high-performance cemented carbide. What is the preparation method of high crystallinity tungsten carbide powder?

Compared with the negative electrode made of tungsten disulfide alone, the tungsten disulfide carbon nanotube negative electrode material has better rate performance and cycle stability, and is more suitable for participating in the production of sodium ion batteries. What is the preparation method of tungsten disulfide carbon nanotube anode material?

In order to overcome the shortcomings of the existing technology, chemical researchers designed a method for preparing nano-tungsten disulfide with a fullerene structure. 

The conventinal autoclave soda leaching is a mature method for treating tungsten concentrate, where tungsten concentrate reacts with sodium carbonate to produce sodium tungstate. And finally through ion exchange and evaporative crystallization, ammonium paratungstate (APT) was manufactured. However the mass waste water is produced during the process.

To ensure the electromagnetic characteristics and processing quality and efficiency of cutting magnetic components, the properties of nonmagnetic and good wear residence of Forming die and cutting tool are the major factors.

The applications of nanocrystalline tungsten oxide (WO₃) include electrochromic, photochromic, gasochromic and sonochromic devices, as a photocatalyst for water splitting and purification, for photoelectrochemical decomposition of water, in heterogeneous catalysts. With the excellent gas sensitivity, another important application is gas sensors.

As an important solid lubricating material, tungsten disulfide has a wide range of applications in aerospace, machining, new energy vehicles, medical, electronics, digital and other fields due to its excellent tribological properties. However, the carrying capacity of pure WS2 film is low, and it is easy to absorb moisture and oxidize in humid air, which seriously shortens its service life.
