Growing Crystals - MIT

Even though growing crystals is more of an art than a science and luck is a major factor, there are some things to do and some other things not to do. The following paragraphs mention some of the more important ones. First some theoretical background about crystallization.

Crystallization - Separation Technology - Articles ...

 The second chief mechanism in crystallization is called secondary nucleation. In this phase of crystallization, crystal growth is initiated with contact. The contact can be between the solution and other crystals, a mixer blade, a pipe, a vessel wall, etc. This phase of crystallization occurs at lower supersaturation (than primary nucleation) where crystal growth is optimal.   ...

Crystallization - an overview | ScienceDirect Topics

In the laboratory, typically glassware or small crystallization vessels are used. In production, vessels are either glass or glass lined, or are made of stainless steel. The vessels are equipped with a cooling/heating jacket and a distillation device. Stirrers are normally impellers or of the anchor type. Few vessels are baffled, the only device acting in this respect is often the temperature ...
