Abstract

β-phase nucleation and growth is an important step in the microstructure development of Si₃N₄ ceramics. Samples containing different powder types, sintering additives and α/β ratios were heated at intermediate temperatures and times to monitor the phase changes taking place. The rate of transformation was mainly dependent on the powder surface area and starting β-content. It was observed that additions of β-Si₃N₄ increased the rate of transformation.
