Spherical crystallization
WebJun 4, 1982 · Abstract Direct spherical agglomeration of salicylic acid crystals during crystallization is described. The needle-like salicylic acid crystals simultaneously form and agglomerate in a mixture of three partially miscible liquids, such as water, ethanol, and chloroform, with agitation. WebSpherical crystallization is the novel agglomeration technique that can transform directly the fine crystals produced in the crystallization process into a spherical shape. This technique of particle design of drugs has gained great attention and importance due to the fact that crystal habit (form, surface, size and particle size distribution ...
