用缓慢升温法在高压釜中生长了α-AlPO4单晶体;用传输法测量了室温下α-AlPO4单晶体的压电、弹性和介电常数,研究了晶体中缺陷对电性能的影响。Samples of Berlinite(α-AlPO4) have been grown by slow heating method in autoclave. The piezoelectric constants and elastic constants have been measured by transmission method at room temperature. In addition, the influence of various defects in crystals on electric properties were studied.
