kristalgroepeilingen

Kristalgroepeilingen is a term found in some Dutch-language crystallization literature to describe the systematic collection and analysis of crystal growth data across a range of experimental conditions in order to map growth behavior and kinetics. The concept focuses on aggregating measurements of growth rates, morphologies, and driving forces to identify robust trends and to infer underlying mechanisms.

The methodology typically combines experimental measurements of growth under varying temperatures, supersaturation, solvents, and impurities with statistical analysis. Data sources include in situ optical microscopy, X-ray diffraction or scattering, and, in some cases, spectroscopic techniques. The term polling or peiling reflects the practice of compiling a dataset from multiple experiments to derive growth-rate laws and kinetic parameters and to compare results across conditions.

Applications of kristalgroepeilingen appear in pharmaceutical crystallization for polymorph control, materials science for semiconductor or ceramic crystal growth, and nanocrystal synthesis. The approach can aid process design by highlighting condition ranges that yield desired crystal forms and growth behaviors.

Advantages of this approach include enhanced cross-condition comparability, improved parameter estimation, and better understanding of how variables influence growth. Limitations include anisotropy of growth (face-dependent rates), measurement uncertainties, data incompleteness, and potential biases from selective reporting. The term itself is not broadly standardized and is mainly found in a subset of Dutch-language sources; in other languages, related work may be described under crystallization kinetics or growth-rate studies.
