说明

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。

Structure of Sr-substituted photosystem II at 2.1 A resolution and its implications in the mechanism of water oxidation.

Faisal Hammad Mekky Koua et al.

Proceedings of the National Academy of Sciences of the United States of America, 110(10), 3889-3894 (2013-02-22)

Oxygen-evolving complex of photosystem II (PSII) is a tetra-manganese calcium penta-oxygenic cluster (Mn4CaO5) catalyzing light-induced water oxidation through several intermediate states (S-states) by a mechanism that is not fully understood. To elucidate the roles of Ca(2+) in this cluster and
