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.

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?

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. 

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?
