Historical and Uses - ALl about calcium

Calcium metal burns in air to give a mixture of white calcium oxide and calcium nitride. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.


Other high quality greases use metal to metal to generate the temperature 90 to 130 C necessary to activate the chemical E.P. used in boundary lubriion protection. Grease’s E.P. solids offer the advantage of giving a continuos E.P. action irrespective of temperature and long before boundary lubriion conditions occur.
