研究了用缓慢升温法生长的α-AlPO4晶体的弹性温度特性。测量采用传输法,测温范围为-30—150℃;用最小二乘法拟合弹性-温度曲线;用电子计算机处理数据。给出了弹性常数cij和sij(i,j=1,2,…,6)的温度特性方程以及T0=25℃时的一级、二级和三级温度系数。Samples of berlinite (α-AlPO4) have been grown by slow heating method. The thermal behavior of elastic prepeties have been studied by transmission method from 30℃ to 150℃. The equations for the temperature behevior of elastic constants have been obtained by polynomial least square method and the 1st, 2nd and 3rd order temperature coefficients of the elastic constants have been calculated (T0=25℃).
