Total or partial coating of powder particles in a nitrogen non-ionic post discharge coupled with a fluidized bed carrying the powder

摘要

The individual coating of powder particles by deposits of a product originating from reactions of diverse molecular precursors with a non-ionic remote post discharge of nitrogen doped or non-doped with another gas, is put into operation by a coupling between the remote post discharge of nitrogen and a fluidized bed entraining the powder or by a falling particles reactor.
