dissolution of small crystals or sol particles and the redeposition of the dissolved species on the surfaces of larger crystals or sol particles.
Notes:
  1. The process occurs because smaller particles have a higher surface energy, hence higher total Gibbs energy, than larger particles, giving rise to an apparent higher @[email protected]
  2. Modified from previous definition. The definition proposed here is recommended for its inclusion of @[email protected] particles.
