摘要：
In a process of preparing single crystals of strontium barium niobate of the type wherein melt of a mixture of strontium oxide, barium oxide and niobium pentoxide is prepared and a single crystal of strontium barium niobate is grown from the melt by using a seed crystal, the compositions included in region A or B shown in FIGS. 2 and 3 are used as the ternary compositions of strontium oxide, barium oxide and niobium pentoxide in the melt.
