A simple method for the preparation of monophasic β‐SiAlON using nitridation of Si and AIN with an oxygen partial pressure of 10 ‐4 atm is described. The effect of the AIN/Si ratio in the initial mixture on the formation of β‐SiAlON is discussed. The likely mechanism of the formation of β‐SiAlON is outlined.
