School of Materials and Metallurgy, Northeastern University, China [Pg.77]

In this paper, the influence of alumina LOI (loss on ignition) on the dissolution behavior of alumina in cryolite-based melts was investigated. Besides bath temperature and bath composition, the dissolution rate of alumina depends on its physicochemical properties such as particle size distribution, density, specific surface area, crystal structure, and LOI.
