Ca(1+x)/2Sr(1+x)/2Zr4P 6-2xSi2xO24 (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.
