Will iron react with calcium oxide? - Answers
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base.
Calcium oxide - wikidoc
Calcium oxide is usually made by the thermal decomposition of materials such as limestone, that contain calcium carbonate (CaCO 3; mineral name: calcite) in a lime kiln. This is accomplished by heating the material to above 825° C ,  a process called calcination or lime-burning , to liberate a molecule of carbon dioxide (CO 2 ); leaving CaO.
