Calcium (CAS NO.7440-70-2) is used as a reducing agent in the extraction of other metals, such as uranium, zirconium, and thorium,as a deoxidizer, desulfurizer, or decarbonizer for various ferrous and nonferrous alloys and used as an alloying agent used in the production of aluminium, beryllium, copper, lead, and magnesium alloys. It is used in the making of cements and mortars to be used in construction.,in the making of cheese, where calcium ions influence the activity of rennin in bringing about the coagulation of milk.

Oxygen (CAS NO.7782-44-7) is used for primary metals manufacturing, chemicals manufacturing, oxidation processes, and partial oxidation processes. The steel industry prefers to use pure oxygen rather than air in processing iron. The oxygen reacts with elemental carbon to form carbon monoxide, which is processed with iron oxide so that carbon is incorporated into the iron metal, making it much lower melting and more pliable (fusible pig iron).

Oxygen is also used medically for patients who require mechanical ventilation, often at concentrations above 21% found in ambient air.

In other oxygen applications, metal fabrication involves cutting and welding with an oxygen-acetylene torch. Chemical manufacture use includes the formation of ethylene oxide, acrylic acid, propylene oxide, and vinyl acetate. Miscellaneous uses include sewage treatment, aeration, pulp and paper bleaching, and missile fuel.
