WebIn the last decade crystal growth from solution under microgravity conditions has been studied extensively to grow a wide variety of crystals such as zeolites, compound … Nucleation can be either homogeneous, without the influence of foreign particles, or heterogeneous, with the influence of foreign particles. Generally, heterogeneous nucleation takes place more quickly since the foreign particles act as a scaffold for the crystal to grow on, thus eliminating the necessity of creating a new surface and the incipient surface energy requirements. diamond plate cleaner for fire trucks
