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.

Although the prevalence of aluminium-related bone diseases has declined, osteomalacia still persists at a low prevalence. The redistribution of bone disease prevalence corresponds to evolving regimens in the treatment of renal disease. Studies have demonstrated an association between the accumulation
