Abstract
IT has already been found that calcium carbonate exists in one stable form, β-CaCO3 (calcite), and two unstable forms, λ-CaCO3 (aragonite) and μ-CaCO3 (or vaterite), in the ordinary temperature range. Aragonite is formed if precipitation is carried out at a temperature approaching the boiling point of water (higher than 85° C.), whereas when precipitation is carried out at room temperature only calcite results. The third form of calcium carbonate, μ-CaCO3, is formed by precipitation at 60° C.1. Barium carbonate and strontium carbonate have only one stable form (aragonite-type structure) and in both cases temperature of precipitation has no effect on crystal form.
