Abstract

Process and apparatus for producing metal particles (12 or 32) from molten metal (2) using a gas flow to comminate a thin film (11 or 11a) of metal formed on an angled portion (6 or 26) of a surface (5 or 25) wetted by the metal (2). The angled portion (6 or 26) subtends an angle of from 5 to 120°. Preferably any rounding (8) of the edge (7) or point (27) de­ fined by the angle should have a radius of curvature of from 4 to 25µm. Free flowing particles (12 or 32) are obtainable.
