Ostwald ripening

dissolution of small crystals or sol particles and the redeposition of the dissolved species on the surfaces of larger crystals or sol particles.
  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.
