Interaction of molten silicon with silicon aluminum oxynitrides
Journal Article

· J. Am. Ceram. Soc.; (United States)
Silicon aluminum oxynitride solid solutions (sialons) based on ..beta..-Si/sub 3/N/sub 4/ and Si/sub 2/N/sub 2/O behave differently in contact with molten silicon. The Si/sub 2/N/sub 2/O-based sialons convert to almost pure Si/sub 3/N/sub 4/, apparently through a two-step decomposition and solution-precipitation reaction, whereas, the ..beta..-Si/sub 3/N/sub 4/ sialons are preferentially attacked at the grain boundaries. The composition of the grain-boundary phase appears to control the rate of reaction.
