Abstract :
The mode of occurrence and the origin of cracking of 3-inch diameter Li2B4O7 single crystal during growth have been investigated. From these considerations, growth conditions for crack-free single crystal have been examined and crack-free 3-inch diameter lithium tetraborate (Li2B4 O7) single crystals by Czochralski method have been successfully grown
