Modifications of 10%‐Pb‐doped Bi 0.5 Na 0.5 TiO 3 were studied for consideration as possible high‐temperature dielectrics. Composition with potassium gave a broader dielectric response and a lower temperature of the ferroelectric‐antiferroelectric transition. With La doping, a low‐temperature‐stable dielectric constant was obtained. Barium modifications increased the dielectric constant and also lowered the first transition temperature. However, doped with 10% Ba, the composition ordered and the first transition ceased to exist.
