WebJul 19, 2024 · Crystal yield, polymorphism, crystal shape, and size distribution of the final particles are some of the key factors that dictate the success of a crystallisation. Based on the product requirements, some of these or related parameters can be monitored during crystallisation and can be used to control the process. WebIn this technique, the 3D size distribution of crystals in a rock (CSD 3D,cor) is calculated by measuring the 2D size distribution in cross-section (CSD 2D) and employing stereological techniques to convert 2D observations into 3D ( Higgins, 2000 ).
