Abstract
Ternary orthophosphates of zirconium, samarium, and alkaline-earth ele ments (MSmZr)-Sm-II(PO4)(3) (M-II-Mg, Ca, Sr, and Ba), Sr0.5(1+x)SmxZr 2-x(PO4)(3), and Sr(2.5-1.5x)SmxZr(PO4)(3) were prepared. The concentr ation and temperature conditions of occurrence of the NZP structure in these series of orthophosphates were studied by various physicochemic al methods (XRD, IR spectroscopy, and DTA). The thermal expansion of S r1.5Sm2(PO4)3 in the 20-800 degrees C range was investigated by high-t emperature X-ray diffraction analysis.
