Tungsten carbide has a special corrosion resistance "high hardness" excellent fracture toughness and compressive strength and is widely used in cemented carbide industry.

Tungsten carbide has been used as a catalyst instead of platinum, rhodium, palladium, iridium and ruthenium as catalysts in some important chemical reactions, which can meet the demand of catalysis and save money.
 
Tungsten carbide can be used in the manufacture of new energy battery, compared with pure hydrogen for hydrogen, with natural gas, methanol, gasoline and other hydrocarbons by reforming reaction site for gas or liquid fuel for fuel cell power generation high energy density, high energy conversion efficiency, convenient transportation, easy to supplement. In the past because of this type of battery only platinum catalyst, the cost is too high and difficult to spread, but now, tungsten carbide complete solve the cost problem, the near future, this kind of battery will soon appear in our mobile phone, tablet, laptop computer.
 
Using methane as the main component of natural gas due to its large reserves and is considered to be a promising source of hydrogen, the conversion of methane to syngas, including steam reforming, dry reforming of methane and carbon dioxide oxygen reforming three methods, the traditional methane synthesis gas reaction with platinum and other rare precious metals as a catalyst, the cost is higher than gasoline, but it is the role of tungsten carbide catalyst, the cost of natural gas dropped significantly, we can see the streets running natural gas taxi.
 
Hydrazine is a liquid fuel used in rocket propulsion, and platinum is also used as catalyst in production, after the use of tungsten carbide, scholars found that the effect is almost the same, but it will produce carbon deposition, so scholars have also added helium He, decomposition generated N2 and NH3.
 
Tungsten carbide catalysts are widely used, but it needs to be explained that the conductivity of tungsten carbide is not strong, but there are still some limitations relative to platinum, but this problem has been solved now, with the large-scale application of the king of new materials, "graphene", it has been found that the preparation of nano-form of tungsten carbide and graphene made of composite catalyst can solve the problem of weak conductivity of tungsten carbide catalyst.
