Relative supersaturation and supercooling in fluxed melt systems

This paper reports the investigation of relative supersaturation and supercooling in solutions of Dy2O3 in K2O · 2MoO3 and K2O3 · 3MoO3, which result in DyKMo2O8 crystals when cooled. It is shown that the relative supersaturation required for nucleation on platinum is higher in melts of the former compositions which yielded fewer, larger crystals. In each case, the degree of critical supercooling is proportional to the absolute saturation temperature, and it is shown that this also applies to the fluxed melt systems which yield Ho2Si2O7 and TbVO4. Measurements were made by thermogravimetric analysis (TGA), under conditions comparable to flux growth by slow cooling.
