CaCO 3 ( s) → CaO ( s) + CO 2 ( g) Calcium carbonate reacts with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate . CaCO 3 ( s) + CO 2 ( g) + H 2 O ( l) → Ca (HCO 3) 2 ( aq) This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions.
The CaCO 3 -based coating was then fabricated on the pore surface by an alternate soaking process. The resulting mineral coating is composed of CaCO 3 nanoparticles which are much smaller than the pore diameter and distributed evenly on the pore surface throughout the membrane, ensuring the separation performance of membranes.

Calcium carbonate coating often refers to coating ground calcium carbonate powder with stearic acid to change the property of GCC powder. Stearic acid is water soluble, and will react with calcium carbonate particles to form a surface coating of calcium stearate.
Coating Calcium Carbonate with Stearate THE PROBLEM Calcium Carbonate is a commonly used filler in plastics compounding. Typically, a stearate coating is required to improve dispersibility of this additive into the compounding process. Traditional coating processes can form undesirable agglomerates that increase the amount of additive required.
