Abstract

Monolithic and composite Si₃N₄, hot-pressed with 6% Y₂O₃, were analyzed using X-ray diffraction and transmission electron microscopy (TEM). The results showed the materials to be composed of β-Si₃N₄ grains and an intergranular phase which was partially crystalline and partially amorphous. It was observed that the amount of intergranular crystalline phase decreased as whiskers were added to the material and the intergranular crystalline part had a crystallographic structure similar to those oxides in the yttrium-silicon-oxide-nitride family.
