By measuring ultrasonic velocity in Li₂SO₄–MgO–P₂O₅:CuO glasses we have evaluated different elastic coefficients; the values of these coefficients exhibited an increasing trend with increase of CuO concentration. Such increase is attributed to increasing presence of copper ions in monovalent state that cross link with phosphate structural units. Such increased degree of augmentation is predicted to be responsible for the increased magnitude of ultrasonic velocities and hence elastic coefficients of the titled glasses.

声波传播研究CuO掺杂对Li ₂ SO ₄ -MgO-P ₂ O ₅玻璃体系弹性性能的影响

通过测量Li ₂ SO ₄ -MgO-P ₂ O ₅：CuO玻璃中的超声速度，我们评估了不同的弹性系数。随着CuO浓度的增加，这些系数的值呈现出增加的趋势。这种增加归因于与磷酸盐结构单元交联的单价态铜离子的存在增加。预测这种增加程度的增加是导致超声波速度增加的幅度的原因，并因此导致标题玻璃的弹性系数增加。
