Computer-controlled crystal growth of KDP from aqueous solution

A system is reported for computer-automated crystal growth of potassium dihydrogen phosphate (KDP) from aqueous solution. The system is based on a real-time cross-correlation between the concentration, temperature and electrical conductivity of the growth solution. The system enables automated super...

Summary:A system is reported for computer-automated crystal growth of potassium dihydrogen phosphate (KDP) from aqueous solution. The system is based on a real-time cross-correlation between the concentration, temperature and electrical conductivity of the growth solution. The system enables automated supersaturation control to within ±0.10 g KDP/100 g water (±0.30% relative supersaturation) of a programmed target value and has been used to grow KDP crystals as large as 13 × 2.5 × 2.5 cm 3 at rates up to 4.5 mm/day in the Z direction.
