PURPOSE: To provide an LiTaO3 single crystal material capable of reducing the rate of generation of pores generated at random in the entire inside of a single crystal when this single crystal is produced by a pulling method with a Pt-Rh crucible. ;CONSTITUTION: In a single crystal material based on Ta2O5 and Li2O3, the average particle diameter of Ta2O5, powder measured by a gas passing method is regulated to 0.70-0.80μm.;COPYRIGHT: (C)1993,JPO&Japio
