An experimental study of the particle characteristics of the magnesium carbonate crystals formed by the reaction between magnesium chloride and sodium bicarbonate at different temperatures is described. The rate of growth of magnesium carbonate crystals for any constant temperature is established, and this rate of growth is related to the degree of supersaturation at the given temperature. The activation energy, calculated using empirical constants derived from the relationship between the crystal growth rate and supersaturation, is indicative of a surface-reaction mechanism.
