A laboratory continuous mixed‐suspension, mixed‐product‐removal crystallizer was used to study the effects of temperature on the kinetics of crystallization of potassium nitrate. A differential refractometer was used to continuously monitor the supersaturation permitting the measurement of supersaturation levels of order 10 −3 Kg solute/Kg water. The nucleation rate exhibited an inverse relationship with temperature.
