The band gap of tungsten bronze (MxWO₃) is about 2.7 eV, and it has free-migrating electrons. It is one of the most suitable materials for transparent and thermal insulation. Research shows that tungsten bronze materials have better transparency and heat insulation than ITO, ATO, AZO and GZO. It is one of the effective means of saving energy for building or automobile glass. It is a kind of high quality filter for infrared light, and it can be coated on the surface of glass or plastic film to form a transparent insulation coating.

Generally speaking, it is a good way to separate tungsten carbide powder by electrolysis. The methods of recovering tungsten carbide by the usual electrolysis process are not completely electrolyzed, the cobalt can not be completely separated and removed and the surface wear of the crusher and ball mill is introduced into the process. The Fe, Ni, Co and other impurities in the tungsten carbide powder are over 0.6%, respectively, and the production of high performance cemented carbides is produced. There is a big gap between the high purity technical standards of Fe, Ni and Co, which are not more than 0.1%, so that the scope of the use of tungsten carbide in the electrolysis process is greatly limited.

In the process of hydrometallurgy of tungsten, sodium tungstate solution is adsorbed by ion exchange resin, and the wastewater is discharged directly. Due to the limitations of the ion exchange process and the complexity of the raw materials, the WO₃ content in the wastewater after ion exchange is always maintained at a certain value, most of which are larger than 0.05g/l. This not only increases the cost of production and consumption of tungsten resources, but also increases the cost of environmental management.

The rock drilling speed is one of the important indicators for the quality of tungsten carbide button bit. In the case of fixed models, lithology, operating systems, etc., the geometric parameters of the bit have a great influence on the rotational speed. The geometric parameters of the button bit include its shape, number, diameter, the distribution of button, the powder discharge system, the tooth height, incline angle of side teeth and so on
