The Science Behind Tungsten Carbide Rod Production
The
Tungsten carbide rod production on a complex chemical process involving high temperatures and precise control over reaction kinetics. Typically, it begins with the reduction of tungsten oxide, often using hydrogen gas, creating finely divided tungsten powder. This powder is then mixed with a carbon source, commonly bitumen or graphite, and formed into rods or other shapes. The crucial step is carbide formation, occurring during sintering at extremely high temperatures, usually between 1400-1600 degrees Celsius, under pressure. This promotes diffusion of carbon atoms into the tungsten lattice, resulting in the desired compound. Careful management of the atmosphere – often vacuum or inert gas – prevents oxidation and ensures complete carbide transformation.
