Abstract
Trivalent cation-doped sodium zirconium phosphates Na1-xMxZr2-xP3O12 (M: In , Yb, Er, Y, Dy, Tb, and Gd; 0 less than or equal to x less than or equal t o 2) were prepared, and their solubility Limit and electrical conductivity were examined. There exist two types of NASICON-related phases, previously reported (M-NZP) and newly observed ones (NMP; x = 1.0-1.9 for M = Yb, Er, Y, Dy, and Tb). NMP is a metastable phase and easily absorbs water. Arrheni us plots show linearity within the M-NZP phase region while some kinks with in the NMP phase region, indicating the difference of the conduction mechan ism between both phases, (C) 1999 Elsevier Science B.V.
