strontium phosphate chemical formula is Sr3(PO4)2. It is a crystalline substance that has many applications. It is an important chemical raw material and analytical reagent, as well as a promising phosphor host material with diverse luminescent properties upon doping with rare earth elements.
Like all metals, strontium is a metalloid that can combine with non-metals to form ionic compounds. In the case of strontium phosphate, both strontium and phosphate ions can lose or gain electrons. The number of electrons lost by the cation (strontium) must be balanced by the number of electrons gained by the anion (phosphate).
Strontium is used in the production of cathode ray tubes for televisions, although these are rapidly being replaced by other technologies. The element is also used in pyrotechnics and fireworks, and radioisotopes of strontium are useful in certain medical treatments. In nature, strontium is found primarily in celestite and strontianite.
When exposed to water, phosphides quickly decompose, evolving toxic and flammable gases. In the case of strontium phosphorus, it is extremely incompatible with oxidizers and will react vigorously with them to produce phosphine gas, which ignites readily. It is therefore advisable to use protective gear such as masks and gloves when handling phosphides and other dangerous chemicals. In the event of a spill, immediate precautions should be taken. See ERG Table 1 – Initial Isolation and Protective Action Distances for guidance. American Elements produces to many standard grades when applicable, including Mil Spec (military grade), ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
