43ca NMR

Ca NMR data were reported for calcium peroxides formed in the disproportionation of EI202 catalysed by Ca(OH)2.36 19F, 27Al, 29Si and 31P MAS-NMR spectra were used to study the structures of samples in the... [Pg.134]

Si02-Al203-P205-Ca0-CaF2 system.37,38 A method has been developed for probing the local structural environment of calcium by natural abundance 43Ca NMR spectroscopy. The method was applied to, for example, sol-gel-prepared calcium silicate materials.39... [Pg.135]

Early observations of calcium in the solid state used either double resonance178 in CaF2 or adiabatic demagnetization at low temperature.179 H-43Ca CP was one of the first experiments that reported more conventional NMR spectra.180 CP used a 46 kHz spin-locking field on the protons that was matched to the central transition of the calcium. Optimum CP was achieved with a contact time of... [Pg.154]
