Pb in Sol-Gel Prepared Ceramics

4 in sol-gel prepared ceramics. Pyrolysis of sol-gel-derived precursors of lead zirconate titanate ceramics and their subsequent crystallisation has been followed using ° Pb MAS NMR (Brieger et al. 1998). Since the spinning rate was not fast enough to narrow the resonance, its width must be due to chemical shift dispersion, which appears however to be reduced on recrystallisation, since this process is
