x
IIZr(PO4)3, BII = Mg, Ca, Sr, Ba (0  x 2) and Na5-3x

x
Zr(PO4)3 (0 x 1.33) were synthesized and studied under heating. The coefficients of thermal expansion along crystal axes

were calculated, and their dependences on the cationic composition (nature and concentration) and on the occupancy of out-of-framework structural positions were established. |
