Solid State Reaction Study of the System Li2C03/Fe203
نویسندگان
چکیده
A thermoanalytical (TGA/DSC) and diffractometric (XRD) study has been performed on the solid state reaction system L i 2 C 0 3 F e 2 0 3 in the xLi range 0.10-^0.50. A detailed analysis of the results shows that the data are in agreement with a reaction model where the carbonate decomposition is regulated by the formation of both L i F e 0 2 and L i F e 5 0 8 , and the relative amount of the two phases depends on the initial composition. The DSC evidence offers the possibility to directly quantify the LiFe5Ox phase. Furthermore it allows one to obtain the enthalpies of formation of both L i F e 0 2 and L i F e 5 0 8 .
