An investigation into the strength characteristics of ceramics based on diphosphates Ca(3–x)М2x (PO4)2 (x = 0–1 and М = Na, K) provides evidence of composition strengthening in the range х = 0.6–0.8 containing the greatest amount of the supercooled high-temperature modification α-СаМРО4. The method of high-temperature x-ray diffractometry is used to examine thermal expansion of rhenanite phases of СаМРО4.
