20100183816 | LOW VELOCITY OXYGEN-FUELED FLAME SPRAY METHOD AND APPARATUS FOR MAKING FERRITE MATERIAL PRODUCTS AND PRODUCTS PRODUCED THEREBY - A method for making ferrite powder may include providing ferrite feed materials in a form of particles, such as having different sizes and irregular shapes. The method may further include exposing the ferrite feed materials to a low velocity oxygen-fueled (LVOF) flame spray. This may 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 LVOF flame spray system for exposing the ferrite feed materials to the flame spray. | 07-22-2010 |
