General description
锶是一种具有银色光泽的二价碱土金属。它是一种活性还原剂，容易与氧、硫和卤素反应。它被广泛用于制备压电式电光学设备的锶基光学材料和骨再生用生物活性玻璃。
Application
用于制备铌酸钾锶（Sr2KNb5O15，SKN）。SKN 非常适合应用于热电传感器和各种电光装置。2
用于津特尔相 SrSn3Sb4 的固态合成，它具有一个 30 元环的阴离子通道骨架。
由于锶可以增进前成骨细胞（preosteoblastic cell）的复制并刺激骨形成，它可用作制备骨再生用生物活性玻璃的前体。

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

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).
