Nano Tungsten Disulfide Producing

Nano tungsten disulfide due to its good performance and broad application prospects is widespread concern, there are many experts and scholars prepared a lot of research on it. However, tungsten disulfide natural mineral is relatively rare, general produce by chemical method to extraction, chemical synthesis method can produce high purity, low impurities and fine granular sulfide oxide. On the other hand it can produce different functional requirements sulfide oxide, therefore chemical synthesis method for produce nano tungsten disulfide has been widespread concern. But it also makes production costs high tungsten disulfide nano particles.
Currently, There are many methods for produce tungsten disulfide, such as ammonium tetrathiotungstate thermal decomposition method, hydrogen sulfide reduction method, high-energy ball milling method, carbon nanotubes space limitations method, hydrothermal synthesis method, hydrogen sulfide or sulfur vapor reduction method, high energy physics and chemistry combine method and so on. So that producing methods of nano tungsten disulfide general can be divided into two types, namely, direct reaction of tungsten and sulfide to form tungsten disulfide or making them react to form reaction precursor and then by ecomposition or reduction with appropriate to generate tungsten disulfide nanoparticles.
