Process for obtaining mixed oxides of calcium and cobalt using shells of bivalve molluscs

摘要

The present invention relates to a process for obtaining cobaltitas calcium (mixed oxides based on calcium and cobalt) using shells of bivalve molluscs (shellfish, mussels, oysters, scallops,Etc.) as a source of calcium ions.The compound obtained can be used in systems of chemical / thermal energy conversion into electricity.The example of thermoelectric devices and solid oxide fuel cells operating between 600 and 800 u00b0 C.
