Super fine tungsten carbide particle has an electronic structure similar to platinum, with high surface energy and chemical activity. It can be used not only as a catalyst but also as a hydrogen electrode material for fuel cells.
Characteristic
Super fine tungsten carbide particle are fine in size and has high surface energy and chemical activity. There are still slight agglomerations in actual production. In the production process, it is necessary to select and add an appropriate inhibitor to further which ensure the uniformity and dispersibility of the powder, and prepare for the industrialized production of the nano tungsten carbide.
Preparation
The traditional technological process suitable for large-scale industrial production: ammonium paratungstate→rotary furnace calcination→tungsten oxide→hydrogen reduction furnace→tungsten powder→carbon tube furnace carbonization→realization of superfine tungsten carbide particle production.
