From Strontian a small Scottish town.
"Strontium" in different languages.

Sources
Found in minerals celestite (SrSO4) and strontianite (SrCO3). Primary producers are China, the UK, Tunisia, Russia, Germany, Mexico and the USA. Around 137 thousand tons are produced annually.
Used in flares and fireworks for its crimson colour. It's primary use is glass for colour television cathode ray tubes, but it is also used in nuclear batteries in buoys, some sensitive teeth toothpastes (as SrCl2), magnets, zinc refining and phosphorescent paint.
Strontium titanate (SrTiO3) has an extremely high refractive index and an optical dispersion greater than that of diamond, making it useful in a variety of optics applications.
