Single crystals of Sr2CaWO6 have been prepared by sintering at high temperature. Powder samples were compressed into rods and heated up to 1953 K. This seems a promising new route for further studies of the structure and physical properties of double perovskites. The structural model of Sr2CaWO6 includes a quantitative description of the twinning shown by the diffraction pattern that should be present in almost any single‐crystal specimen for this type of compound.
