General description

Strontium is a divalent alkaline earth metal with a silvery luster. It is an active reducing agent and readily reacts with oxygen, sulfur, and halogen. It is widely used in the preparation of Sr-based optical materials for piezoelectric, electro-optic devices, and bioactive glasses for bone regeneration.

Application

For the synthesis of biomaterials and superconducting materials, the raw materials must be pure. Therefore, in order to achieve the desired performances, it is crucial to reduce undesired metals or interfering elements. For the synthesis of premium new materials, our 99.99% trace metal-based strontium beads are the best option.
Elemental Strontium has wide applications. For example, Superconducting Strontium Germanide (SrGe3) Containing Ge2 Dumbbells is synthesized at high pressure and high temperture using metallic Stronium. Strontium is also used in low temperature solution process to synthesize strontium doped oxide with high carrier mobility, enhanced electrical stability for thin film transition.
In addition, Strontium is applied in the solid state synthesis of a Zintl phase, SrSn3Sb4, with an anionic channel framework of 30-membered rings. Interestingly, Strontium is used to synthesis the crack free Strontium-potassium-niobate (Sr2KNb5O15, SKN) thin films by using chemical solution deposition method. SKN is of great interest for pyroelectric sensors and various electro-optic devices.
Further more, Strontium (Sr) has also been investigated as a bioactive element capable of stimulating bone tissue regeneration.According to the literature, bioactive-glass incorporated with Sr has recently received a lot of attention for various orthopaedic applications that combine the effect of BG surface bioactivity with the promotion of bone growth due to Sr-controlled release.[5]
Used to make Strontium-potassium-niobate (Sr2KNb5O15, SKN). SKN is of great interest for pyroelectric sensors and various electro-optic devices.2
