The kinetics of crystal melting for sodium disilicate have been determined over the temperature range 875-884°C. When compared with previous data on crystallization kinetics, melting is found to take place much more rapidly than crystallization. The reduced melting rate is found to be independent of superheat, and the interface morphology in melting is non-faceted. It is suggested that the crystal-liquid interface in melting is rough on an atomic scale.
