The Leachability of Calcium Aluminate Phases in Slags for

It is apparent that the leachability of a phase affects that of other phases. A less leachable phase could hinder the leachability of a more leachable phase. The experimental data shows that the leaching rate of slag from highest to the lowest is CaO.Al2O3, 3CaO.Al2O3, and CaO.2Al2O3, respectively.

Calcium Aluminate - sarmad shamim

Calcium aluminate (CaAlO3) refractories are usually derived from calcium aluminate, calcium, or alumina-bearing minerals. Calcium aluminate is used in refractory cements and shapes, as well as synthetic slag additions for metallurgical operations. Most carbon steel operations aim for minimal slag carry-over. A new slag cover is “built” during tapping. For ladle furnace operations, a
