* Calcium hydroxide solution ( Ca ( OH )< sub > 2 </ sub >) ( also known as limewater ) is used to detect the presence of carbon dioxide by being bubbled through a solution.

* Calcium hypochlorite ( Ca ( OCl )< sub > 2 </ sub >) is used as a swimming pool disinfectant, as a bleaching agent, as an ingredient in deodorant, and in algaecide and fungicide.

* Calcium phosphide ( Ca < sub > 3 </ sub > P < sub > 2 </ sub >) is used in fireworks, rodenticide, torpedoes and flares.

* Calcium stearate ( Ca ( C < sub > 18 </ sub > H < sub > 35 </ sub > O < sub > 2 </ sub >)< sub > 2 </ sub >) is used in the manufacture of wax crayons, cements, certain kinds of plastics and cosmetics, as a food additive, in the production of water resistant materials and in the production of paints.

* Calcium sulfate ( CaSO < sub > 4 </ sub >· 2H < sub > 2 </ sub > O ) is used as common blackboard chalk, as well as, in its hemihydrate form better known as Plaster of Paris.

Calcium sulfoaluminate cements are made from clinkers that include ye ' elimite ( Ca < sub > 4 </ sub >( AlO < sub > 2 </ sub >)< sub > 6 </ sub > SO < sub > 4 </ sub > or C < sub > 4 </ sub > A < sub > 3 </ sub > in Cement chemist's notation ) as a primary phase.

Calcium to phosphorus ratios should be 2: 1 to prevent hypocalcemia, sometimes known as hind leg paralysis ( HLP ).

Calcium released by basalts binds up CO < sub > 2 </ sub > from the atmosphere forming CaCO < sub > 3 </ sub > acting thus as a CO < sub > 2 </ sub > trap.

When the cement paste exposed to the air and meteoric water reacts with the atmospheric CO < sub > 2 </ sub >, portlandite and the Calcium Silicate Hydrate ( CSH ) of the hardened cement paste become progressively carbonated and the high pH gradually decreases from 13. 5 – 12. 5 to 8. 5, the pH of water in equilibrium with calcite ( calcium carbonate ) and the steel is no longer passivated.

** Calcium < 2 mmol / L

* Calcium < 2 mmol / L
