Abstract

A method and apparatus for powder surface treatment by turning the powder into a fluidized layer while passing gas made, at least partially, of a reactive gas, through the powder, to improve dispersion stability of powder pigments. Since the powder is turned into the fluidized layer by gas made, at least partially, of reactive gas, powder particles are put in close and uniform contact with the reactive gas, ensuring full surface treatment of the powder.
