Abstract :
Sintering tests in a gyrotron installation have been performed in order to study the densification behavior of nanostructured ceramics under MM-wave radiation. It was shown that MM-wave sintering is superior to conventional heat treatment. In order to reach the desired densities with the MM-wave technique the necessary processing times are markedly shorter and the sintering temperatures are lower.
