Detailed Product Description:

White, crystalline powder, odorless, alkaline taste.  Soluble in

water and glycerol.  Insoluble in alcohol.  Non combustible.

Calcium carbonate is a common substance found in minerals in

all parts of the world, and is the main component of shells of marine

organisms.  Calcium carbonate is the active ingredient in agricultural

lime, and is usually the principal cause of hard water.  It is commonly

used medicinally as a calcium supplement or as an antacid.

Chemical properties

Calcium carbonate shares the typical properties of other carbonates, notably,

it reacts with strong acids releasing carbon dioxide.  Calcium carbonate

will react with water that is saturated with carbon dioxide to form the

soluble calcium bicarbonate. 

Calcium carbonate is known as whiting in ceramics/glazing applications

where it is used as a common ingredient for many glazes in its white

powdered form. When a glaze containing this material is fired in a kiln,

the whiting acts as a flux material in the glaze.

Also used in swimming pools as a pH corrector for maintaining alkalinity

"buffer" to offset the acidic properties of the disinfectant agent.

It is commonly called chalk as it has been a major component of blackboard
