COATING METHOD AND COATED PARTICLE

Japanese Patent JP2004017020

A

To provide a method for coating the surfaces of first particles uniformly with second particles smaller than the first particles and the first coated particles coated with the second particles uniformly to be resistant to peeling.

The surfaces of the first particles 20 are coated with the second particles by fluidizing the first particles 30-10 μm in average particle size, producing the drops of a suspension with the second particles 5-500 nm in average particle size smaller than that of the first particles suspended, from a spray nozzle 40 etc., and making the first fluidized particles 20 collide with the suspension drops. The surfaces of the first particles 3-10 μm in average particle size are coated with the second particles 5-100 nm in average particle size.
