ABSTRACT:
A process for heating powder materials by microwave radiation so that heating and sintering or melting progressively and directionally occurs within the powder materials. The process generally entails forming a structure from a powder by arranging the powder in a mass according to size of particles of the powder so that the particles are progressively arranged within at least a region of the mass from smallest to largest. The mass is then subjected to microwave radiation so that the particles within the mass progressively couple with the microwave radiation according to size, the smallest particles coupling first and heating faster than larger particles of the powder, and the largest particles coupling last and heating slower than smaller particles of the powder. As a result of the progressive arrangement of the particles, the mass is progressively and directionally heated by the microwave radiation.
