## Abstract Understanding the mechanisms of growth and inhibition during crystallization of calcium sulfate is of primary importance for many industrial applications. For instance, inhibition of the crystallization process may be required to prevent scale formation in pipes, boilers, heat exchanger
## Abstract Aqueous supersaturated solutions of Calcium Sulphate Dihydrate (Gypsum) have been magnetically treated by passing the former at high velocities through fields of permanent magnets and also using the “Polar Water Conditioner”. No effects have been observed on either the nucleation or the
