Jan 22, 2021· What do they use strontium for? Strontium is used for producing glass (cathode ray tubes) for color televisions. It is also used in producing ferrite ceramic magnets and in refining zinc. The world's most accurate atomic clock, accurate to one second in 200 million years, has been developed using strontium atoms.
Abstract: Ceramic magnets as barium ferrite or strontium ferrite have many applications in high technology. One of the reasons is the low cost when compared to competitor materials, as Alnico, MnBi, MnAl or NdFeB. In this study, the advantages and disadvantages of Ba and Sr ferrite …
Crystalline, submicrometer strontium ferrite powders, including SrFeO 2.97, SrFe 2 O 4, Sr 2 FeO 4, Sr 3 Fe 2 O 6.16, and SrFe 12 O 19, were prepared by spray pyrolysis of an aqueous solution of mixed metal nitrates.The Sr:Fe mole ratio in the precursor solution was retained in the final products.
