A new phase in the Si-Al-O-N system has been identified, following syntheses based on the nitridation of silicon/clay mixtures at low temperatures (a combination of diffraction and high-resolution imaging techniques, and this new phase possessed the same sheet structure as O′-SiAlON (Si2-xAlxO1+xN2-x) but with a different stacking arrangement. It is considered to be a low-temperature polymorph of O′-SiAlON and transforms to conventional O′-SiAlON at temperatures greater than ～1350°C.
