Insights into utilization of strontium carbonate for thermochemical energy storage

open access: yesRenewable Energy, 2020
The reversible dissociation/carbonation of metal carbonates, performed in fluidized bed reactors, is one of the most promising technological solution for thermochemical energy storage (TCES) in concentrating solar power plants (CSP). In this framework, the SrCO3/SrO system is receiving increasing interest due to its high energy density (4 GJ/m3) and ...

Multi-layered Barium and Strontium Carbonate Structures Induced by the Small Organic Dye Acid Orange 7. [PDF]

open access: yesCryst Growth Des, 2021
The crystal growth behavior induced by small molecular additives is commonly assumed to be far less complex and rich in comparison to that obtained when using macromolecules. Herein, we demonstrate that the small organic molecule Acid Orange 7 can induce

Calcination of Strontium Carbonate in Rotary Kiln Furnace

open access: yes10th International Symposium on High-Temperature Metallurgical Processing, 2019
The calcination of the strontium carbonate in the rotary kiln is usually carried out at temperatures as high as 1300 °C in practical applications. During the calcination process, partial melting of powders occurs at about 1150 °C, due to the partial pressure of CO2.
