Strontium phosphate (Sr3(PO4)2)

Description:
Strontium phosphate, with the chemical formula Sr3(PO4)2 and CAS number 7446-28-8, is an inorganic compound that appears as a white crystalline solid. It is composed of strontium cations (Sr²⁺) and phosphate anions (PO4³⁻), forming a stable ionic lattice structure. Strontium phosphate is relatively insoluble in water, which limits its use in aqueous applications but makes it suitable for certain solid-state reactions and applications in ceramics. The compound exhibits low toxicity and is often used in various fields, including materials science and biomedicine, particularly in bone-related applications due to strontium's role in bone health. It can also be utilized as a phosphor in luminescent materials. Strontium phosphate can be synthesized through various methods, including precipitation from strontium and phosphate sources. Its thermal stability allows it to withstand high temperatures, making it useful in high-temperature applications. Overall, strontium phosphate is a versatile compound with significant relevance in both industrial and research settings.
