Thermal evolution of the (444) cubic reflection splitting located in the interval ( $82^{\circ}<2 \theta<{ }^{\circ} 86$) for the $\mathrm{Sr}_{2} \mathrm{Co}_{1-x} \mathrm{Mg}_{x} \mathrm{TeO}_{6}$ compounds with $(x=0.1,0.2,0.5)$. The splitting of the triplet (404), (-404) and (044) is clearly seen at 300 K and as temperature increases, the reflections get closer, up to 870 K where they remain as a single peak.
