Calcium doping levels of up to 20 % can be achieved for the La 1− x Ca x OCl 1− x solid solution series. At the highest doping levels ( x =0.2; see graph (•)), the conductivity of the solid solution is three orders of magnitude greater than that of undoped LaOCl (□). The potential for the design of new functional materials stems from their high thermal stability, relative density, and hardness, in addition to their insolublity in water.
