How synthesis parameters influence the quality of lead magnesioniobate PbMg1/3Nb2/3O3
Autor: I. N. Smirnova, G. V. Zimina, F. M. Spiridonov, E. S. Nassonov
Publikováno v: Russian Journal of Inorganic Chemistry. 57:797-801
Lead magnesioniobate PbMg1/3Nb2/3O3 (PMN) has been prepared using lead oxide and magnesium niobate. Factors that influence the perovskite/pyrochlore ratio in the PMN structure have been studied. In order for the maximal amount of the perovskite phase
