摘要：

High purity (Ba1-xCax)(Ti1-yZry)O-3((x,y) = (0.00, 0.00) - (0.50, 0.50)) were synthesized by a composite-hydroxide-mediated approach at 200 degrees 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 k(r) was 36.1% ((x, y) = (0.05, 0.03)) and highest mechanical quality factor Q(m) was 256 ((x, y) = (0.11, 0.13)).
