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

Redox-inactive metals are found in biological and heterogeneous water oxidation catalysts, but, at present, their roles in catalysis are not well understood. Here, we report a series of high-oxidation-state tetranuclear-dioxido clusters comprising three manganese centres and a redox-inactive metal (M).

Osteoporosis is an important age-related bone disease characterized by increased bone turnover with insufficient bone formation relative to bone resorption. According to the current understanding of this disorder, anti-resorptive and anabolic drugs have been developed for therapeutic intervention. Another therapeutic
