Abstract
A method of enhancing the flowability of a powder. The powder is defined by a plurality of particles having an initial level of inter-particle forces between each particle. The method comprises: treating the powder, wherein the level of inter-particle forces between each particle is substantially decreased from the initial level; fluidizing the treated powder; flowing the treated powder into a plasma arc chamber; the plasma arc chamber generating a plasma arc; and the plasma arc chamber operating on the treated powder using the generated plasma arc. Preferably, the inter-particle forces are decreased by coating the particles with an organic surfactant.
