A thermogravimetric method has been developed and is suggested for both the
qualitative and quantitative phase analyses of high-calcium lime and calci
um speciation as well. Two complementary TG measurements are proved to be s
atisfactory for the determination of moisture, calcium oxide, calcium hydro
xide and calcium carbonate contents as well as total mineral impurities in
high-calcium limes: quicklime, hydrated lime and limestone.
