Abstract
The growth installation and peculiarities of growth Li₂B₄O₇ (LBO) crystals by Czochralsky method have been described in this paper. Experimental results of temperature dependences of ultrasonic velocities for various modes and crystallographic directions were measured and some anomaly in this dependence was discovered. Our results are discussed in comparison with some previous data.
