摘要：
The effect of agitation on crystallization behaviors of CaO-Al2O3-SiO2-Na2O-CaF2 mold fluxes with basicity of 1.1 and 1.2 was investigated. It was found that crystallization temperatures of agitated samples were higher than those of static samples. The morphology of cuspidine shifted from dendrites to facet crystals with the decrease of temperature. The agitation was conducive to the formation of small dendritic cuspidine and could lead to crystals with smaller size. Crystalline fraction could be significantly enhanced by agitation at the initial stage of crystallization. (C) The Minerals, Metals & Materials Society and ASM International 2015
