Title: Production of single crystal
Inventor: KASHIWABARA NAGATAKE
IPC: C30B29/54
Filed: 1988-02-29
Abstract: PURPOSE:To industrially produce layer and uniform single crystal by a simple method by raising the concn. of a soln. within a specified range together with growth of single crystal and controlling growth velocity of a crystalline line in case of obtaining single crystal in a soln. method. CONSTITUTION:In case of obtaining, e.g., single crystal of urea from an aq. soln. in a crystal tank 1, the size of single crystal is sensed with a video camera 8 and the concn. of the soln. in the tank 1 is gradually raised at supersaturation degree not more than 1.1 so that the growth velocity of a crystalline line is controlled. In this case, the flow rate to the tank 1 fitted with a jacket from a solute dissolving tank 2 fitted with the jacket is controlled with a quantitative pump 5 joining the tanks 1, 2 in which controlling temp. of + or -0.1 deg.C is obtained by circulation water fed from the thermostatic chambers 3, 4 and the tanks 1, 2 are regulated at 45 deg.C and the tank 1 is made to a saturated state at 45 deg.C and thereafter regulated at 44 deg.C and seed crystal 6 is hung. At this time, the tank 2 is held at 45 deg.C and the soln. is circulated to the tank 1 from the tank 2 at 0.2ml/min flow rate just after addition of the seed crystal 6. Thereafter, the above-mentioned flow rate is gradually raised because the growth velocity of the crystalline line is made slow as single crystal is grown and the surface area thereof is made large.
