Description
The main objective of this analysis was to study the structure of samples synthesised by the amorphous seed method. The implications of this process upon the synthesized material were unknown. In the synthesis it was used ethanol and amorphous seed, which were added to the final synthesis mixture. It was observed a very significant reduction in the reaction time when compared to conventional synthesis. NMR was used to study the defects in the crystal lattice. Results are presented and discussed
