Abstract
Microwave processing of silicon nitride-based ceramics is currently being examined to identify aspects that may accelerate densification or produce unique microstructures. Because the microwaves preferentially couple with the sintering additives and the intergranular phases, relatively high additive contents are required to produce samples that will densify and are crack-free. Improved densification of green powder compacts and enhanced weight losses are observed during microwave heating.
