High purity (Ba1-xCax)(Ti1-yZr y)O3((x,y)=(0.00,0.00)(0.50,0.50)) were synthesized by a composite-hydroxide-mediated approach at 200°C using a sealed tube with a rolling system. The powders with an average size of 50 nm in diameter and narrow size distribution were produced. The highest electromechanical coupling factor kr was 36.1% ((x,y) = (0.05,0.03)) and highest mechanical quality factor Qm was 256 ((x,y) = (0.11,0.13)).
