Crystallization

A.  During most crystallizations, C/Csat (concentration/saturated concentration) is kept near 1.02 to 1.05









B.  Crystal growth rates and crystal sizes are controlled by limiting the degree of supersaturation.









C.  During crystallization by cooling, the temperature of the solution is kept 1-2 °F (0.5-1.2 °C) below the saturation point at the given concentration.









D.  A generally acceptable crystal growth rate is 0.10 - 0.80 mm/h
