PROCESS FOR THE TREATMENT OF PARTICLES USING A PLASMA TORCH

摘要

The present invention relates to a process for the treatment of particles using a plasma torch and to the particles obtainable by said process. The process for the treatment of particles comprises the steps of: (A) providing particles, comprising (a) a substrate and (b) at least one layer on the substrate; or particles, especially platelet-like particles; (B) entraining said particles in a stream of gas for transport to a plasma torch; (C) creating a plasma in said stream of gas to heat the outer surface of the particles; (D) permitting said particles to cool; and (E) collecting said particles.
