Chemical Vapor Synthesis of Uniform Mixtures of Fine Powders

Producing homogeneous mixtures of fine powders using conventional methods can be a challenging task, especially when the mixture is a composite powder. This technology describes a process of synthesizing fine powder mixtures from reactions in the gas phase followed by condensation and surface deposition. It allows sintering at relatively low temperatures, making it possible to mold the mixture into different shapes and sizes. One application of this technology has been to produce a homogeneous mixture of nano-sized tungsten carbide and cobalt mixture from their precursors. The resulting material was both hard and tough unlike pure tungsten carbide.

*The composite powders are used as raw materials for producing bulk pieces used for drill bits and wear components.

Stage of Development
This technology is part of an active and ongoing research program.
