Abstract
Liquid metal undergoes rapid rotational motion in an induction field and utilizes the resultant centrifugal forces to extend the metal in the form of a rotating film, the film becoming progressively thinner, along a baffle surface located in the induction field. The liquid metal can then emerge through the baffle surface in the form of wires or can be reduced in size on a cylindrical impact wall and then cooled.

A method of processing liquid metal using centrifugal forces from a rotating electro-induction field, the induction field setting the liquid metal in rotation inside a rotationally symmetric limiting wall, comprising the further step of:
- causing the centrifugal forces to extend the liquid metal along a baffle surface located in the induction field so that the liquid metal defines a rotating film, said rotating film becoming progressively thinner about the periphery thereof;
- and
- forming said continuously rotating metal film on said baffle surface so thin whereby said periphery of said film is atomized when flung off from said baffle surface.
