Carbon and Strontium Abundances of Metal‐poor Stars [PDF]
The Astrophysical Journal, 2007 We present carbon and strontium abundances for 100 metal-poor stars measured from R$\sim $7000 spectra obtained with the Echellette Spectrograph and Imager at the Keck Observatory. Using spectral synthesis of the G-band region, we have derived carbon abundances for stars ranging from [Fe/H]$=-1.3$ to [Fe/H]$=-3.8$.

Surface complexation model for strontium sorption to amorphous silica and goethite
Geochemical Transactions, 2008 Strontium sorption to amorphous silica and goethite was measured as a function of pH and dissolved strontium and carbonate concentrations at 25°C. Strontium sorption gradually increases from 0 to 100% from pH 6 to 10 for both phases and requires multiple

Microbial formation of crystalline strontium carbonate [PDF]
FEMS Microbiology Letters, 1994 Pseudomonas fluorescens appeared to grow in a mineral medium containing strontium (5 mM) complexed to citrate, the sole source of carbon, without any evident inhibition in cellular yield. Atomic absorption studies showed that the divalent metal was excluded from the cytoplasmic component and was initially found in the supernatant fluid in soluble form ...

Kinetics of conversion of celestite to strontium carbonate in solutions containing carbonate, bicarbonate and ammonium ions and dissolved ammonia [PDF]
Journal of the Serbian Chemical Society, 2014 Celestite concentrate (SrSO4) has been converted to SrCO3 in solutions containing CO32-, HCO3- and NH4+ ions and dissolved ammonia. The effects of stirring speed, CO32- ion concentration; temperature and particle size of SrSO4 on the reaction ...

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2008 In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.
