WebCrystal nucleation theory applied to hydrous magma Examination of natural volcanic products shows that the crystal nucleation kinetics determine crystal number density and ultimately crystal size distributions, and thus govern the texture of crystallized materials. WebThe process of crystal growth includes nucleation, growth and coarsening. For a new phase to grow, a stable embryo of the new phase must from first. This process is called nucleation. The nucleus serves as a template for the crystal to grow. The growth of the crystal involves interface reaction and mass/heat transfer. WebJan 1, 2003 · The formation of the crystal involves two steps: nucleation and growth. When the saturation of a solution exceeds a critical value, crystal nuclei are produced [142, 143].
