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.

Si and nAl NMR and FTIR have been used to study the products of OPC hydration in the presence of a heavy metal containing stabilized waste which is commercially solidified, selected organics and pulverised fuel ash. \*'Si NMR unambiguously quantifies the extent of silicate polymerisation, which is s
A naturally occurring 1.4 nm tobermorite and a synthetic jennite were characterized by 27AI and 29Si magic angle spinning nuclear magnetic resonance (MASNMR) spectroscopy and their cation exchange properties were measured. 27AI MASNMR spectroscopy revealed that both the 1.4 nm tobermorite and synthe
