Question

Define crystallization in 200 words
​

Answer 1

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.

Answer 2

Answer:

Crystallization

Explanation:

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Fundamentals

Crystals, Crystal structure, Nucleation

Concepts

Crystallization, Crystal growth, Recrystallization, Seed crystal, Protocrystalline, Single crystal

Methods and technology

Boules, Bridgman–Stockbarger method, Crystal bar process, Czochralski method, Epitaxy, Flux method, Fractional crystallization, Fractional freezing, Hydrothermal synthesis, Shaping processes in crystal growth.

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.

Crystallization occurs in two major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.
