melt

This method is the most basic. A gas is cooled until it becomes a liquid, which is then cooled further until it becomes a solid. Polycrystalline solids are typically produced by this method unless special techniques are employed. In any case, the temperature must…

In a melt consisting of a single component, such as CaSiTiO₅, all atoms could add to titanite nuclei to form crystals of titanite. If, however, the melt contained 30 percent CaAl₂Si₂O₈, the rate of formation of titanite nuclei would be decreased, as 30 percent of the melt…
