Abstract
The hot-pressing behavior of two amorphous and three crystalline silicon ni tride powders, including both experimental and commercial samples has been investigated in the presence of MgO-Y2O3 sintering aid. The powders were ch aracterized in terms of bulk and surface chemistry, phase composition and m orphology. The sintering behavior was assessed on the basis of green and fi nal densities, weight loss on densification and chemical and phase composit ions of the dense material.
