Substitution of Ca2+ by Sn2+ and Sr2+ cations in P. placenta shells and single-crystal calcite through ion exchange reactions

Materials Research Express, 2021
Tin (Sn ^2+ ) and strontium (Sr ^2+ ) are potential replacements to lead (Pb ^2+ ) in perovskite synthesis since Sn is on the same IVA group in the periodic table as Pb while Sr is a promising alternative according to Goldschmidt’s rules and quantum ...

Performance and Environmental Evaluation of Stabilized Base Material with Strontium Slag in Low-Volume Road in China

Advances in Civil Engineering, 2019
Strontium slag, a by-product of the strontium carbonate refining industry, has been produced at million tons per year in China. The use of strontium slag in the roads could reduce the demand of virgin materials and help solve the environmental problems ...

Incorporation of strontium in earthworm-secreted calcium carbonate granules produced in strontium-amended and strontium-bearing soil [PDF]

Geochimica et Cosmochimica Acta, 2013
This paper investigates the incorporation of Sr into biomineralized calcium carbonate granules secreted by the earthworm Lumbricus terrestris. Experiments were conducted using an agricultural soil amended with Sr(NO3)2 to give concentrations in the range 50 - 500 mg kg-1 Sr and a naturally Sr-rich, Celestine-bearing soil containing up to 11 000 mg kg-1

Reconstruction of deglacial sea surface temperatures in the tropical Pacific from selective analysis of a fossil coral [PDF]

, 2005
The Sr/Ca of coral skeletons demonstrates potential as an indicator of sea surface temperatures (SSTs). However, the glacial-interglacial SST ranges predicted from Sr/Ca of fossil corals are usually higher than from other marine proxies.
