General description

Strontium is a divalent alkaline earth metal with a silvery luster. It is an active reducing agent and readily reacts with oxygen, sulfur, and halogen. It is widely used in the preparation of Sr-based optical materials for piezoelectric, electro-optic devices, and bioactive glasses for bone regeneration.

Application

Applied in the solid state synthesis of a Zintl phase, SrSn3Sb4, with an anionic channel framework of 30-membered rings.
As strontium can enhance the replication of preosteoblastic cells and stimulates bone formation, it can be used as a precursor in the preparation of bioactive glasses for bone regeneration.
Used to make Strontium-potassium-niobate (Sr2KNb5O15, SKN). SKN is of great interest for pyroelectric sensors and various electro-optic devices.2

Although the prevalence of aluminium-related bone diseases has declined, osteomalacia still persists at a low prevalence. The redistribution of bone disease prevalence corresponds to evolving regimens in the treatment of renal disease. Studies have demonstrated an association between the accumulation
