Investigations of many silicate systems carried out in recent years have again confirmed the great value and validity of the rule of successive conversions or simply the stage rule, first formulated by W. Ostwald. Stable phase states with a minimum energy level may be reached in stages through intermediate metastable states, characterized by higher energy levels.
