Secondary nucleation initial breeding

Strickland-Constable (1968) described several possible mechanisms of secondary nucleation, such as initial breeding (crystalline dust swept off a newly introduced seed crystal), needle breeding (the detachment of weak outgrowths), polycrystalline breeding (the fragmentation of a weak polycrystalline... 

Garside etal. (1979) measured size distributions of secondary nuclei and reported their variation with supersaturation. Significant increase of nuclei with supersaturation is observed. Thus the process is not simply an attrition event alone, but is also related to the level supersaturation at which parent crystal is growing. Jones etal. (1986) also observed anomalous growth of secondary nuclei in a study of the continuous MSMPR crystallization of potassium sulphate with consequences inferred for secondary nucleation rates. Girolami and Rousseau (1986) demonstrate the importance of initial breeding mechanism in seeded potash alum batch crystallization. The number of crystals...
