Abstract: An apparatus for producing an inorganic powder and an apparatus for producing and classifying an inorganic powder are provided, wherein the apparatus for producing an inorganic powder includes an insulating tube, at least one pair of annular RF electrodes, and a gas supply apparatus. The pair of annular RF electrodes surrounds the outer circumference of the insulating tube to generate a first electric field region outside the insulating tube and generate a second electric field region having a plasma torch in the insulating tube after being turned on. The gas supply apparatus supplies a reaction mist and an inert gas into the insulating tube to thermally degrade and oxidize the reaction mist into an inorganic powder via the plasma torch.

Abstract: A coating device is provided, and includes a coater and an electrical field generator. The coater contains a slurry or ink and has an outlet. The slurry or ink is coated on a substrate through the outlet. The substrate is disposed adjacent to the outlet, and loads the slurry or ink from the outlet of the coater to form a wet film. The electrical field generator is disposed under the substrate and provides the electrical field, and thus the wet film stacks tightly on the substrate due to the attraction of the electrical field.
