The results of a thermogravimetric study of the catalytic effects of alkaline earth carbonates in the C-CO2 reaction are described. Using graphite powder as the carbonaceous phase the rates of the reaction between 700 and 1100°C were found to be substantially increased on addition of small amounts o
The crystallization of calcium carbonate was carried out by mixing CaCl 2 and Na 2 CO 3 solutions. The morphology of precursor formed prior to the nucleation of the polymorphous crystals (calcite and vaterite) varies depending on the feed concentration. The faster nucleation rate of polymorphous cry
pH changes in Ca(OH) 2 solutions have been studied using a low sodium selective glass electrode. Successive additions of MgCI 2 and MgSO 4 both lower pH whereas Na2SO 4 contamination leads to an increase in pH and NaCI causes no pH change at all. The amount of salt addition required to change pH al
