IC 7933 Strontium - A Materials Survey ? Introduction And Summary

[THE COMPOUNDS of strontium were confused with those of barium until 1790, when A. Crawford discovered that the mineral strontianite, long believed to be a barium mineral, was a compound of a new element. This discovery was confirmed 2 years later by I. C. Hope. The mineral was named strontianite because it was found near the town of Strontian in Argyllshire, Scotland. In 1808 Sir Humphrey Davy isolated strontium metal by the electrolysis of fused chlorides. Celestite (strontium sulfate) and strontianite (strontium carbonate) are the principal strontium minerals. Because of its more widespread occurrence, celestite is more important commercially.]
