Title:
CHARGE BAR FOR RELAXOR-FERROELECTRIC SINGLE CRYSTAL GROWTH, PREPARATION METHOD THEREFOR, AND DEVICE FOR MANUFACTURING CHARGE BAR
Document Type and Number:
WIPO Patent Application WO/2022/206137
Kind Code:
A1
Abstract:
Provided are a charge bar for relaxor-ferroelectric single crystal growth, a preparation method therefor, and a device for manufacturing the charge bar, the method comprising the following steps: step 1): preparing raw materials at the stoichiometric ratio of relaxor-ferroelectric single crystal materials, placing the raw materials in a material melting zone of a container, heating the material melting zone to melt the raw materials and maintaining the temperature; and step 2): then heating a casting control zone of the container, connecting the casting control zone with the material melting zone, such that the molten raw materials remain in a molten state and flow into a mold through the casting control zone, thereby obtaining a charge bar for relaxor-ferroelectric single crystal growth by cooling. Oxygen is optionally introduced into the material melting zone when the raw materials are molten and the temperature is maintained in step 1) and when the molten raw materials flow into the mold through the casting control zone in step 2).
