Strontium and Strontium Compounds

Abstract

Strontium is a hard white metal. Strontium forms 0.02–0.03% of the earth's crust. The principal strontium mineral is celestite, naturally occurring sodium sulfate. The leading producing countries of celestite are China, Mexico, and Spain. World resources are thought to be 1 billion tons. Nearly all strontium metal is produced commercially by the thermal reduction process in alloy steel retorts. The strontium ion has a low order of toxicity and most compounds have a low order of toxicity. Compounds containing the isotope Sr‐90 are the most toxic. The main uses for strontium is in the form of compounds. End uses include in pyrotechnics, and signals, ferrite ceramic magnets, master alloys, pigments and fillers, and the electrolytic production of zinc. Strontium compounds discussed are acetate, carbonate, hexaferrite, halides, nitrate, oxide, hydroxide, peroxide, sulfate, and titanate.

Sr2+ Sustained Release System Augments Bioactivity of Polymer Scaffold

“…Meanwhile, it could reduce bone resorption by inhibiting the differentiation of osteoclasts . However, it should be noted that the strontium usually existed in the form of compounds, and direct introduction into the polymer scaffolds would result in the burst of strontium ion (Sr 2+ ) release, which might bring biological toxicity to normal cells and tissues. , Therefore, seeking a carrier to realize the sustained release of Sr 2+ was urgent.…”

Metallic Strontium as a Precursor of the Al2O3/SrCO3 Xerogels Obtained by the One-Pot Sol–Gel Method

“…Strontium carbonate (SrCO 3 ) takes advantage of the production of X-ray tubes, hard magnets, ceramics, and special glasses [ 8 ]. Before or during the high-temperature production processes, strontium carbonate (SrCO 3 ) is decomposed into strontium oxide (SrO) and carbon dioxide (CO 2 ).…”
