The Thermal Dissociation of Calcium Carbonate.

Abstract: This value agrees well with that determined by Winkler (Seidell, solubilities, page 67) 3.36 g. per zoo g. soln., or approximately 0.206 mol per liter.

“…Johnston 17 and Mitchell 18 determined the equilibrium temperature at which calcium carbonate dissociates at atmospheric pressure to be 1171 K. Both the decomposition temperature and reaction time affect the physical properties of the formed calcium oxide. A high burning temperature and long calcination time yield a hard-burned quicklime that has high density and low porosity; whereas a low burning temperature and short burning duration yield soft-burned lime with low density and high porosity (Boynton 19 ).…”

“…When combustion is used, acid pretreatments are necessary to remove any carbon -containing minerals, such as carbonates, which will decompose at temperatures above 750 ° C (Johnston 1910 ;Armitage et al 2001 ). The fi rst acid treatment dissolves carbon -containing minerals, such as limestone.…”

“…The result is that the Co 2 concentration in the kiln will rise from 20-30 % to over 80 %. The effect of raising the partial pressure of Co 2 on the calcination (thermal decomposition) of limestone © Woodhead Publishing Limited, 2010 has been understood for almost a century (Johnston, 1910). The temperature at which the reaction (equation 15.1) proceeds (i.e.…”
