Rotary shoulder technique for growing sapphire crystal by kyropoulos method
InactiveCN103014842AQuality improvementIncrease profitPolycrystalline material growthUsing seed in meltEngineeringCrystal growth
The invention discloses a rotary shoulder technique for growing sapphire crystal by a kyropoulos method. In the sapphire growth process employing the kyropoulos method, the power is reduced to enter the shoulder stage after seeding of the crystal is finished; the crystal is kept in a rotary state at this stage, and meanwhile, the withdrawal rate of the crystal is kept; the diameter of the crystal is gradually enlarged along with an upward pulling process; rotation of the crystal is stopped when the growth weight achieves 8-10% of inventory; and the crystal enters an equant growth stage in a vertical pulling state. By adopting the rotary shoulder technique disclosed by the invention, vortex rotating along with the crystal is formed by flux on a solid-liquid interface along with rotation of the crystal; and an air bubble gathered on the solid-liquid interface is gradually discharged along with flow of the flux. Therefore, the content of the air bubble can be effectively reduced; the quality and the utilization rate of the crystal are improved; crystal sticking on crucible caused by over-quick crystal growth in one direction and uneven temperature field also can be effectively avoided; molding of the appearance of the crystal is facilitated; subsequent crystal manufacturing procedures are facilitated; the stick cutting rate can be improved; and the product usage is also improved.
