In the present study the possibility of partial decomposition of CaCO3
up to 80 degrees C by using organic acids has been investigated. As a
cids in the acid - CaCO3 reaction, citric and oxalic acid have been us
ed. The formation of the crystalline compounds during the acid reactio
ns as also their decomposition during the burning process have been st
udied through XRD analysis and loss on ignition measurements. The resu
lts led to the conclusion that a variety of organic acids could be suc
cessfully used resulting in energy saving by lowering the decompositio
n temperature.
