Strontium was discovered in 1790 from the mineral strontianite found near the village of Strontian in Scotland. Sir Humphry Davy first isolated the pure metal in 1808 using electrolysis.
Strontium occurs naturally in minerals such as celestite and strontianite. The largest commercial source is celestite, from which most strontium compounds are produced.

Strontium compounds are widely used in fireworks, emergency flares, ferrite magnets, ceramics, glass manufacturing and certain medical applications.
Calcium, Barium, Magnesium and Oxygen
Pure strontium reacts readily with oxygen and water, forming oxides and hydroxides. For this reason, it is stored away from air and moisture.
Electronic Configuration: [Kr] 5s²
Strontium's greatest strength is its ability to produce an intense crimson-red flame, making it indispensable in fireworks and emergency signaling devices.
The brilliant red color seen in many fireworks displays around the world is produced by burning strontium salts.
Strontium nitrate and other strontium compounds emit a vivid crimson-red light when heated. This unique property makes strontium one of the most important elements in pyrotechnics.
Because strontium behaves chemically similar to calcium, it can become incorporated into bones. Certain strontium compounds have been studied for treating bone-related disorders under medical supervision.
Strontium-90 is a radioactive isotope produced during nuclear fission. It is important in environmental monitoring and nuclear safety because it can accumulate in bones.
Strontium ferrite is widely used to manufacture permanent magnets found in electric motors, loudspeakers, household appliances and many electronic devices.
Every time brilliant red fireworks illuminate the night sky during festivals and celebrations, strontium compounds are often responsible for that spectacular color. This remarkable property has made strontium one of the most celebrated elements in pyrotechnics and public celebrations around the world.
Scientists are studying strontium in quantum computing, ultra-precise optical atomic clocks, advanced ceramics, superconductors and biomedical materials.
Like many heavier elements, strontium was formed inside stars through stellar nucleosynthesis and spread across the universe by supernova explosions.
Modern optical atomic clocks based on strontium atoms are among the most accurate clocks ever built, capable of measuring time with extraordinary precision.
