Zinc-containing particles, method of manufacturing such particles by a thermal evaporation-condensation process, and coating composition comprising such particles

Abstract

Zinc-containing particles and a method of manufacturing such zinc-containing particles by a thermal evaporation-condensation process performed in a heated chamber. A zinc-containing source material is supplied to the heated chamber. The heated chamber comprises an evaporation section where the zinc-containing source material is fully or partly vaporized to the gas phase, and a condensation section where zinc vapour is nucleated and/or condensed heterogeneously, and may be collected on a surface, such as a particle collector, in a cyclone or a filter. The zinc-containing particles have special shapes and properties compared to prior art zinc-containing particles. A coating composition comprising such zinc-containing particles.
