Abstract

<PICT:0660541/III/1> Crystals are grown from seeds 9 immersed in a mother solution 1 in a closed container 2 by condensing vapour from the solution and allowing the condensate to return to the mother solution after dissolving more solute. As shown the vapour condenses on the surface of a tube 12 depending into the container and cooled by a cooling liquid in pipe 13. A basket 16 containing solute is suspended below the tube, condensate dripping through the solute back to the solution 1. The crystals 9 are agitated by a vertical or rotary motion. The container is maintained at constant temperature by the thermostatically controlled heating jacket 3.
