METHOD OF MANUFACTURING A DRY POWDER PARTICLE, A POWDER PRODUCED WITH SAID METHOD, AND AN ELECTRODE AND AN APPARATUS FOR USE IN SAID METHOD

摘要

The invention relates to a method of manufacturing a dry powder particle, preferably using electrohydrodynamic spraying, wherein two oppositely charged aerosol streams are contacted. The invention allows for the manufacture of powders having various, controllable compositions and shapes. In particular the method according to the invention may be used to perform physical and chemical reactions and allows for the manufacture of powders not previously obtainable. In addition, the invention also relates to an electrode (4, 4', 5, 10a, 10b) and an apparatus for applying the method according to the invention.
