Coarse Grain Size Crystalline Tungsten Carbide Powder

The coarse grain size crystalline tungsten carbide powder is produced by high-temperature reduction and high-temperature carbonization, and has a series of advantages such as microscopic structure, less defects, high microhardness, and small microscopic strain. It also has a different range of use with medium and fine grain tungsten carbide powders.

In particular, the addition of a small amount of cobalt/nickel carbonized coarse-grain tungsten carbide powder not only accelerates the carbonization process, but also has a considerable degree of coarsening of the grain size. The grain size is 4 to 5 times that of tungsten carbide powder without cobalt carbide. However, it is necessary to compactly load the boat, causing the tungsten carbide powder to be broken and failing to be mass-produced.
