Y-α/β-Sialon Powders by Self-propagating High Temperature Synthesis

Shi Ju Guo

Abstract

Polyphase Y-α/β-Sialon powders were prepared by SHS method, with St, Al, Y2O3 and Si3N4as raw materials under high nitrogen pressure. The effects of nitrogen pressure and the amount ofdiluent on α', β' phase compositions and the amount of free Si were studied in detail.
