Strontium

Occurrence, isolation & synthesis


Occurrence


In nature, strontium is found in the Earth's crust, in minerals such as celestine and strontanite [7]. The isotopes found in nature are 84Sr (0.56 %, stable), 86Sr (9.86 %, stable), 87Sr (7.02 %, stable) and 88Sr (82.56 %, stable) [7].

In pure solid form, strontium exist in a face-centered cubic crystal structure [7]
