摘要
The calcination method is the usual method to synthesize cement clinkers. The production of ordinary Portland cement requires temperatures as high as 1450 degrees C. High amounts of energy are used and huge flows of carbon dioxide are liberated to the atmosphere. In the literature, the combustion method has been often reported as a fast and effective method to prepare ceramics. The precursor solutions are metal nitrates and organic combustibles such as urea or glycine. The oxidation-reduction exothermic reaction is very fast. In this work, the effect of H(2)O(2) addition to the combustion preparation of clinker is discussed. A conventional clinker prepared by calcinations at 1200 degrees C is used for comparison purposes. The combustion preparation with H(2)O(2) as an additive reduces calcination time and temperature.
