Abstract
The growth of crack-free 3-inch-diameter lithium tetraborate (Li2B4O7) Single crystals by the Czochralski method has been studied. The relat ionships between crystal cracking rate during growth and the crystal r otation rate and the position of the work-coil have been examined. It is concluded that crystal cracking at a later stage of growth is relat ed to the temperature fluctuation in melt.
