K. Byrappa et al., CRYSTAL-GROWTH, MORPHOLOGY, STRUCTURE, AND PROPERTIES OF HNAMP2O7 CRYSTALS WHERE M=CO AND NI, Journal of materials research, 9(6), 1994, pp. 1519-1525
The HNaMP2O7 (where M = Co and Ni) new Na+ superionic pyrophosphates w
ere obtained by the hydrothermal method at lower PT conditions (T = 25
0 -degrees-C, P = 100 atm). The solubility, complexation with referenc
e to the solvent-solute interaction, and the growth process have been
studied in detail. A new investigation on the crystal structure of the
se compounds showed that the title compounds do not contain Zr as repo
rted previously. The crystal morphology and properties have also been
studied.
