**Preface to "Advances in Industrial Crystallization"**

Crystallization plays an important role in many manufacturing industries for the production of food, drugs, biopharmaceuticals, flavors, dyestuffs and pigments and agrochemicals, as well as ceramics and metals. Crystallization process design in industry is generally based on key performance indicators (KPIs) which include costs, process parameters, such as yield, productivity and process simplicity, and product properties, such as purity, solid-state form, crystal size and morphology. These KPIs are usually specific for each application. In relation to this connection, the book compiles fifteen articles collected for a first Special Issue of the recently established Industrial Crystallization Section of *Crystals*.

Relating to several of the abovementioned industry sectors, the contributions comprise different current facets of crystallization research, from the very fundamentals up to industrial application. Many of the topics covered may be classified as follows: (i) from the crystallization basics to processes, (ii) crystal shape development, (iii) measurement techniques, (iv) continuous crystallization, (v) process intensification, (vi) melt crystallization and (vii) nanoparticles in crystallization. Most articles are strongly based on challenging experimental work and also involve novel techniques.

The individual articles are introduced in the *Editorial* of the book in the context of the main topics mentioned above.

We thank all authors whose contributions are included in this Special Issue for their excellent work, and their inspiring articles.
