METHOD AND APPARATUS FOR MAKING FERRITE MATERIAL PRODUCTS AND PRODUCTS PRODUCED THEREBY

摘要

A method for making ferrite powder may include providing ferrite feed materials in a form of particles having different sizes and irregular shapes, and exposing the ferrite feed materials to a plasma to provide a more spherical shape to irregularly shaped particles to thereby make the ferrite powder. An apparatus for making ferrite powder may include a feeder for ferrite feed materials and a plasma generator for exposing the ferrite feed materials to a plasma.
