Ca (1+ x )/2 Sr (1+ x )/2 Zr 4 P 6−2 x Si 2 x O 24 ( x ≤ 0.37) compositions, which belong to the [NZP] family of low‐thermal‐expansion materials, were synthesized using the solid‐state reaction method. The lattice thermal expansion of members of this system was determined up to 1000°C by high‐temperature X‐ray diffractometry. The bulk thermal expansion and the microcracking during cooling also were investigated. These properties depended on the composition, on the synthesis method, and on the sintering conditions.
