Abstract
A method for heating metal powder, e.g., iron powder, comprises irradiating the powder with microwaves. The powder may be coated with various materials to enhance the heating effects of the microwave. For example, the powder may be coated with a non-emissive material, such as a ceramic material. The powder may also be coated with a dipole material, such as water or plastic, or a dielectric material.
