The synthesis of (K 0.485 Na 0.485 Li 0.03 )(Nb 0.8 Ta 0.2 )O 3 from a mechanochemically activated powder is presented for the first time. Mechanochemical activation, followed by a single calcination step was found to be a powerful technique for synthesizing a homogeneous solid solution with a low amount of contaminant, coming from the milling equipment, and good electrical properties without the need for a multiple calcination procedure involving intermediate wet‐milling steps, which are typically required in the conventional solid‐state synthesis route.
