Description

一般描述

Dendritic strontium is a form of strontium metal that has a unique, tree-like or branching morphology. It is often made by electrodeposition. Dendritic strontium is a silvery-white metal that is highly reactive with water and oxygen, and it readily tarnishes in air. It has several important physical properties, including a melting point of 769 °C and a density of 2.54 g/cm³.

应用

树突锶可用于津特尔相 SrSn₃Sb₄ 的固态合成，它具有一个 30 元环的阴离子通道骨架。它也可用于制备铌酸钾锶（Sr₂KNb₅O₁₅，SKN），SKN 非常适合用于热电传感器和各种电光装置。
