Abstract The issue of obtaining heterostructures from strontium bismuthate and strontium carbonate is discussed. Effect of increase of photocatalytic activity of such heterostructures at the certain weight ratio of strontium carbonate is discovered. It is shown that increase of photocatalytic activity is correlating to opposite migrations of bismuth ...

Abstract Strontium carbonate with self-activated luminescence in the short-wave length region λ max = 490 nm is obtained by thermal decomposition of pure SrC 2 O 4 · H 2 O at 530°C. By means of EPR, CO 2 − radicals are found in the luminescent strontium carbonate, which are stabilized in anion sites and interstitial positions of the lattice.

The carbonate location in mixed calcium and strontium carbonated apatites
Polyhedron, 2020Abstract Mixed calcium/strontium carbonated apatites were obtained by aqueous addition of mixtures of calcium and strontium nitrate to NH4H2PO4 and Na2CO3 in the presence of both low and high sodium concentrations. The calcium: strontium ratios in the products were obtained by xrf and carbonate percentages by combustion analysis.

The solubility of strontium carbonate in water
Journal of the Chemical Society, Dalton Transactions, 1972Values have been determined for the solubility of SrCO3 in water, by use of both radiometric and flame emission spectrophotometric methods. The two methods gave essentially identical results. For water free from atmospheric CO2 the solubilities/mg I–1 were 5·34 ± 0·014 at 5 °C, 6·94 ± 0·018 at 15 °C, and 8·95 ± 0·029 at 25 °C.

Surface texture of strontium carbonate
Journal of Chemical Technology and Biotechnology, 1980AbstractTwo batches of strontium carbonate (SrCO3) prepared at temperatures ⩽333 K (A) and 373 K (B) were investigated using differential thermal analysis (DTA), thermogravimetric (TG), X‐ray diffraction (XRD) and N2 adsorption techniques. Heat treatment up to 1073 K causes no material decomposition of the carbonate and DTA and TG results indicate ...

Microbiological precipitation of strontium carbonate
2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011In this paper, The strontium carbonate precipitate was induced with the role of the enzymes according to the bacillus pasteurii reproduction in different concentrations of Sr2+. The morphology and structure of strontium carbonate were characterized by X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Scanning Electronic Microscope (SEM).

Effective thermal conductivity of porous strontium oxide and strontium carbonate samples
Journal of Applied Physics, 1999The thermal diffusivity of some pressed powder strontium oxide (SrO) and strontium carbonate (SrCO3) samples has been measured from room temperature to 1400 °C in vacuum and in an argon atmosphere using the laser flash technique. The structures of the samples have been analyzed using a scanning electron microscope and a theoretical model has been ...
