Strontium is a soft, silvery-white or silvery-yellow alkaline earth metal. Natural strontium is a mixture of four stable isotopes — Sr-84, Sr-86, Sr-87 and Sr-88 — and is primarily found within the minerals celestite and strontianite.
Like other alkali metals, strontium is highly reactive chemically and reacts with both air and water. When exposed to air, it burns with a bright red flame. When combined with water, strontium gives off hydrogen gas and strontium hydroxide — a strong irritant.
In the manufacture of fireworks, strontium carbonate, nitrate and perchlorate are used to color flames a crimson-red color. An alloy of magnesium and strontium has powerful pyrophoric qualities and finds application in fireworks for incendiary and flaring compounds, Strontium is added to copper and several of its alloys and to lead alloy batteries, and is used for the desulfurization of cast iron, copper and steel, and also for the reduction of uranium.
Alloys of strontium with tin and lead are used for casting conductors of accumulator batteries. Alloys of strontium and cadmium are used for the anodes of battery cells. Hard ferrites of strontium are widely used as materials for the manufacture of permanent magnets.
Strontium uranate plays an important role in producing hydrogen by the thermochemical method (atomic hydrogen energy), and methods are being developed for uranium fission in strontium urinate, to produce heat in the breakdown of water into hydrogen and oxygen.
Strontium oxide is used as a component in superconductive ceramics. In the solid solution of the oxides of other alkali earth metals – barium and calcium (BaO, CaO) – it is used as an active layer of indirectly heated cathodes in vacuum electronic devices. Strontium fluoride is used as a component of solid-state fluorine batteries with a high energy capacity and energy density.
