29 Si magic angle spinning (MAS) NMR, 27 Al MAS NMR and 27 Al triple-quantum MAS NMR were used to study the dealumination of offretite occurring during hydrothermal treatment. Deformed tetrahedral ( Si-O-) 3 Al-OH species and two octahedral extra-framework species are formed during the course of th
