The significant changes of surface texture in CaCO, crystallites due to reaction in an equimolar SO,-O2 mixture were examined by scanning electron microscopy. Surface modifications were extensive above 870 K, which is close to the temperature of CaCO, dissociation and of CaSO, oxidation. It appears

The combustion of sulfur-containing coal particles on a calcium carbonate crystal results in retexturing of a neighbouring CaC03 (100) face. The structural modifications developed at the CaCO, crystal surface show similarities to those found after reaction of calcite in SO, and O2 (air). It is concl
