Stishovite, a high-pressure SiO2 polymorph in which each Si is coordinated by six O atoms, transforms to an amorphous phase when undergoing heat treatment below the glass transition temperature at ambient pressure. We have applied 29Si magic angle spinning nuclear magnetic resonance spectroscopy (MA
27AI and 2~Si magic-angle spinning(MAS) nuclear magnetic resonance(NMR) and complementary X-ray diffraction (XRD) studies of carbothermal formation of sialons from kaolinite and halloysite confirm that the reaction involves the initial formation of mullite (3AI203.2SIO2) and amorphous silica. In the
