5.1 Strontium in materials chemistry

In its natural state, strontium is mainly found as carbonate (SrCO ₃ , strontianite) and sulfate (SrSO ₄ , celestine). A very large number of synthetic materials also contain this element. For example, until recently, strontium-containing glass was used in CRT televisions to slow down X-ray emissions. In the field of microelectronics, Sr titanate (such as SrTiO ₃ ) and Sr niobate (such as SrNb ₂ O ₆ and Sr ₂ Nb ₂ O _...
