Abstract
The yield of flat powder (6) of Al, Mg or their alloy is enhanced by forming, on a rotary cooling body (4), a film (8) which can prevent the flat metal powder (8) from sticking to the cooling surface. The film (8) adheres to the cooling surface at a force which is sufficient for forming the film but which enables the film material to adhere to the flat powder which then separates from the cooling body (4). The film consists essentially of at least one liquid lower fatty acid and at least one solid higher fatty acid.
