Polymorphism in crystallisation
Webpolymorphism, in crystallography, the condition in which a solid chemical compound exists in more than one crystalline form; the forms differ somewhat in physical and, sometimes, … WebThe techniques for seeding of a desired polymorph during crystallisation from solutions are reviewed. The basic informa- tion about the type of polymorphism needed to consider seeding strategies is discussed first. The development of seeding strate- gies is facilitated by certain data on the system.
