Structural characterization of mullites synthesized by thermal decomposition of topaz

The structure of mullite obtained by thermal decomposition of topaz at 1340 C and after additional thermal treatment at 1600 C was characterised by 29Si and 27Al MAS NMR spectroscopy and XRD. No amorphous phase was detected. The 29Si MAS NMR spectra of the mullite samples showed four resonance peaks...
