Abstract
A process is disclosed for producing metal flakes. The process involves entraining the metal powder particles in a carrier gas and passing the powder particles through a high temperature zone at a temperature above the melting point of the powder particles to melt at least about 50% of the powder particles, resolidifying the resulting high temperature treated material by impacting the material against a substrate, and thereafter contacting the material with a non-oxidizing gas which can be nitrogen, argon, hydrogen, helium or combinations of these to remove the material from the substrate in the form of flakes.
