Claims13
Composition in the form of thermally treated briquettes comprising a “quick” calcium-magnesium compound selected from the group consisting of quicklime, magnesian quicklime, dolomitic quicklime and quick calcined dolomite, and an iron-based compound in the form of calcium ferrite, characterized in that said calcium ferrite forms a matrix, the matrix being a continuous phase of calcium ferrite in which particles of said “quick” calcium-magnesium compound are dispersed.
Composition in the form of thermally treated briquettes made by baking green briquettes at a temperature between 1050° C. and 1200° C. for a time between 5 and 25 minutes, comprising a “quick” calcium-magnesium compound selected from the group consisting of quicklime, magnesian quicklime, dolomitic quicklime and quick calcined dolomite, and an iron-based compound in the form of calcium ferrite, characterized in that said calcium ferrite forms a matrix, the matrix being a continuous phase of calcium ferrite in which particles of “quick” calcium-magnesium compound are dispersed.
