Synthesis of Hydrogarnet from Blast Furnace Slag Using Alkali Fusion for HCl Gas Removal

Blast furnace (BF) slag, one of the by-products iron- and steel-making plants, was converted into product including hydrogarnet using alkali fusion method for HCl gas removal. The slag with diameters less than 2 mm transformed alkali-fused reactive phases via sodium hydroxide at 600°C 6 h, after which fused added to distilled water stirred room temperature prepare precursor synthesize a by heating 80-160°C. could remove high (800°C), Cl fixation in follows pseudo-first-order kinetics model rather pseudo-second-order model. These results suggest that novel able can be synthesized from BF fusion.
