Title: Forming method for single crystal of lithium tantalate into single domain
Inventor: ENOKIDA KENJI
IPC: C30B29/30
Filed: 1981-12-07
Abstract: PURPOSE:To form a single crystal of LiTaO3 into a single domain in a less cracked state in the stage of applying a prescribed electric field at prescribed temp. to said single crystal by starting the application at temp. lower than the specific values. CONSTITUTION:Electrodes 4 are provided at both ends of the Z-axis of a single crystal 3 of LiTaO3, and are inserted into an electric furnace 2. Voltage, for example, 60V is applied from lead wires 5 by turning a switch on. Electricity is conducted to the heater 1 in the furnace 2 to heat up the furnace gradually. If the single crystal is maintained for about 20min at 650 deg.C when the crystal attains said temp., the single crystal is formed approximately in a single domain. Thereafter, the furnace temp. is reduced gradually and when the temp. of the single crystals falls to 150 deg.C, the application of the electric field is ceased and when the temp. falls to 60 deg.C, the single crystal is removed, whereby the single domain treatment is completed. The rate of generation of cracks is extremely low. If the application of the electric field is started when the temp. is <=500 deg.C even if it is not before the starting of heating, the rate of generation of cracks decreases similarly.
