“…The supercooling for crystallization of the slag B is remarkably larger than that of slag D, and thus, crystal in the slag B is more likely to be dendritic as shown in Figure 4. Interestingly, the present findings are in quite good agreement with Lu et al [23] and Heulens' [26] experimental results regarding the alpha-Ni crystal and wollastonite morphology evolution under different supercooling degrees.…”

“…In the present manuscript, n ðhklÞ is considered as 1 for a simplification in the same manner as done by other authors. [26] In this case, how to calculate the enthalpy of dissolution DH m is the key point to obtain the Jackson a factor as a crystal morphology criterion, which will be introduced in the following part in detail.…”

“…As the experimental temperature decreases, or with higher undercooling, the faceted interfaces become unstable and change into dendritic crystals. [7,18] At an intermediate temperature of 1543 K (1270°C), the faceted crystal assumed to be C 3 A grows and the degree of constitutional supercooling increases with continuous precipitation of C 3 A as the liquidus temperature rises, which thus accelerates dendritic growth to increase the surface area for higher heat extraction. Considering the characteristics of the CLSM, a temperature gradient exists between the crucible wall and the melt.…”

“…Thus, depending on the chemical composition of the melt and the cooling conditions, distinct differences in the primary crystal phases and the morphology were observed. In a more recent study by Heulens et al [7] , isothermal crystallization in the CaO-Al 2 O 3 -SiO 2 system was accelerated by wo¨llastonite particles, which resulted in a faceted crystal being observed at 1643 K (1370°C) and a dendritic nonfaceted crystal being observed at 1593 K (1320°C).…”
