Embodiment Construction
[0021] The invention discloses a method for raising the temperature of a pre-cast shape filler in a sapphire growth crystal. The heating system is started, and the temperature rises from 25°C to 1650°C, wherein the temperature rise slope is 200°C / h; when the temperature reaches 1650°C, Modify the temperature increase slope to 30°C / h, and raise the temperature to 2000°C until the block is completely melted.
[0022] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
