Abstract

See full text

This coating device 1 comprises a dispersing/mixing part 2, a conveying part 3, and a collecting part 4. A raw material powder and a coating solution are supplied to the dispersing/mixing part 4 as a slurry. In the dispersing/mixing part 2, the slurry (mixture) in which the raw powder and the coating solution have been mixed is dispersed by means of an air flow of a high-pressure fluid into a powder, a film of the coating solution having adhered to the surface of the powder. The powder is introduced from the dispersing/mixing part 2 to the conveying part 3t and is conveyed with the conveying part 3 oriented toward the collecting part 4. While the powder is being conveyed, the coating solution that has adhered to the particle surfaces dries, whereby a powder in which the particle surfaces ares coated with a precursor is produced. A powder flow introduced into the collecting part 4 passes through a bag filter 54. This causes the powder to be captured by the bag filter 54.
