Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calciumsupplement

Dispersing agents Functionality & Performance
Dispersion MechanismApplicationsOptimum DosageIonic dispersing agents act by coating the surfaces of inorganic mineral particles as the result of an attraction to the positive charges that develop on particles when in contact with water, a process known as ‘adsorption’. Adsorption imparts a net negative charge to the particle surface so that the particles are repelled from each other. When a mineral is dispersed in water using Dispex products, this negative attraction reduces the interactioSee more on dispersions-pigments.basf
