Descripción

General description

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.

Application

Se utiliza para sintetizar niobato de estroncio y potasio (Sr₂KNb₅O₁₅, SKN). El SKN es de gran interés para los sensores piroeléctricos y varios dispositivos electro-ópticos.²

Dendritic strontium has a number of important uses including use as a component of alloys, as a material for pyrotechnic devices, as a reagent in the production of ferrite magnets, and as a dopant in the production of semiconductors.

Dendritic-strontium can be applied in the solid state synthesis of a Zintl phase, SrSn₃Sb₄, with an anionic channel framework of 30-membered rings.It can also be used to make strontium-potassium-niobate (Sr₂KNb₅O₁₅, SKN) which is of great interest for pyroelectric sensors and various electro-optic devices.
