ABSTRACT:
The invention provides a method of producing ultra-fine particles and an apparatus therefor. A particle carrier is moved in a chamber which is decompresed and charged with inert gas. An evaporable material is heated so as to deposit evaporated ultra-fine particles onto a part of the moving particle carrier. The deposited ultra-fine particles are collected from the part of the moving particle carrier while evaporated ultra-fine particles deposit onto another part of the moving particle carrier.
