Embodiment
[0024] see figure 1 , the present invention provides a kind of crystal growth method, grow crystal in the crystal growth furnace, improve and integrate the original seeding process, the original inherent single seeding method (crystallization seeding or continuous seeding) integrated into the same novel seeding process, specifically, see figure 2 , including a first growth stage and a second growth stage in sequence, the first growth stage adopts a crystallization seeding process, and the second growth stage adopts a continuous seeding process.
[0025] see image 3 In the chart in the figure, the crystal diameter of the first growth stage ranges from 15 to 25mm, the first growth stage is at least composed of the first step of crystal seeding and the second step of crystal seeding, and the crystal diameter of the first step of crystal seeding The range is 15~20mm, the crystal amplification rate of the first step of crystallization seeding is 0.3~0.5mm / min, preferably 0.4mm / ...
