钒酸钙中发现了铁电性。通过切克拉尔斯基拉法生长出了大而透明的晶体。通过刻蚀生长晶体观察到毫米尺寸的180°电畴。铁电居里温度Tc = 1383 K，由介电、热电和热释电研究确定。
Ferroelectricity has been discovered in calcium vanadate. Large, transparent crystals have been grown by Czochralski pulling. Electrical 180° domains of millimeter dimensions are observed by etching as-grown crystals. The ferroelectric Curie temperature, Tc = 1383 K, has been determined from dielectric, thermal and pyroelectric studies.
