1524624 Crystal growth by electrolysis NORTH AMERICAN PHILIPS CORP 12 March 1976 [17 March 1975] 09967/76 Heading BIG Crystals are grown by preparing a saturated aqueous solution of a water soluble ionisable salt, the dissociated cation of which is less reducible than H<SP>+</SP> and the dissociated anion of which is less oxidisable than OH-, subjecting the saturated solution to electrolysis thereby causing the solution to lose water under isothermal conditions and crystals of the salt to form. It is preferred to use a seed crystal rotating on a shaft on which crystal growth can take place. Evaporation of solution can be prevented by floating an immiscible liquid, e.g. oil, on the surface of the aqueous solution. The growth of several salts is exemplified including potassium sulphate and lanthanide sulphates. |
