  • Crystallization process
    Patent number: 4309501
    Abstract: Fine crystals characterized by improved morphological homogeneity and a narrow size distribution are prepared by introducing a solution of a crystallizable solute in a solvent into a bed of small inert continuously moving solid particles and initiating crystallization within the solution while it is in contact with the moving particles. The process finds application in the manufacture of diverse crystalline products such as, for example, in the formation of metal oxalates, phosphorescent compounds, and silver halide crystals, as well as in the purification of both organic and inorganic materials.
    Type: Grant
    Filed: July 9, 1980
    Date of Patent: January 5, 1982
    Assignee: Eastman Kodak Company
