Document Type and Number:
WIPO Patent Application WO/2021/223557
Kind Code:
A1
Abstract:
Disclosed are a crystal preparation apparatus and a crystal growth method. The apparatus comprises a growth cavity which is used for crystal growth, and a temperature control system which is used for heating the growth cavity and ensuring that the radial temperature difference in the growth cavity during crystal growth does not exceed a first preset range of the average temperature in the growth cavity. The method comprises: placing a seed crystal and a source material in a growth cavity for crystal growth; and in the process of crystal growth, controlling a heating component on the basis of information from a temperature sensing component, so that the radial temperature difference in the growth cavity during crystal growth does not exceed a first preset range of the average temperature in the growth cavity.
