The hot-pressing behavior of two amorphous and three crystalline silicon nitride powders, including both experimental and commercial samples has been investigated in the presence of MgO-Y2O3 sintering aid. The powders were characterized in terms of bulk and surface chemistry, phase composition and morphology. The sintering behavior was assessed on the basis of green and final densities, weight loss on densification and chemical and phase compositions of the dense material.
