Calcium Carbonate Powder

Calcium carbonate powder is an extremely important material both in basic research and in industry. It has been used as filler for paints, pigments, coatings, paper and plastics and can be molded by organisms into complex and beautiful shapes, such as bones, teeth and shells. Calcium carbonate powder can mainly exist in four polymorphs: calcite, vaterite, aragonite and amorphous calcium carbonate (ACC), of which calcite is the most thermodynamically stable phase. The ACC phase is unstable and relatively short-lived and serves as a seed for the crystal growth of the other polymorphs. Calcite, vaterite and aragonite have typical rhombohedral, spherical and acicular morphologies (shapes) respectively. Typical morphologies of the different polymorphs of Calcium carbonate powder. The worldwide availability of CaCO3 (as limestone), its compatibility and non-toxicity to the human body make the synthesis of this material an exciting and exciting topic for scientists and researchers to study. Therefore, numerous studies have been conducted to stabilize specific polymorphs of CaCO3 in different sizes and with exotic morphologies. There are two important synthesis methods for this: the biomimetic method and the CO2 sparging method. The first method attempts to mimic nature’s ability to synthesize different shapes and sizes by using soluble organic compounds and physiological parameters. Bubbling CO2 into slaked lime is the current method of industrial synthesis. The synthesized CaCO3 particles as such have a number of beneficial properties and thus may have numerous applications in addition to their current use as filler material, e.g. catalysis, drug delivery vehicles, models for other functional materials and biosensors..
