The process of forming a crystalline structure from a liquid or dissolved in the liquid is often regarded as the crystallization. In ancient times, for example, about the meaning of the word Root crystal, water undergoes a cooling phase change liquid solid starting with small ice crystals that grow until they meet, form polycrystalline structure. The physical properties of the ice depends on the size and positioning of various crystals or grains, and one can say the same Bank as a starting point for metals from a molten state.
The structure of liquid crystal depends on the chemistry of fluids, the conditions under which it is strengthened, and the ambient pressure. During the cooling of the rule to mean that the production of a crystalline material, under certain conditions, the liquid can be frozen in a state noncrystalline. In most cases, this is the coolant, as soon as the atoms can not travel to their schedules sites, before losing mobility. A noncrystalline equipment, in order, it is not large, there is talk of an amorphous, vitreous or vitreous material. It is also often regarded as an amorphous solid, but there is a clear difference between the masses and glasses: first of all, the process of forming a glass does not exempt the latent heat of fusion. For this reason, many scientists believe glass materials viscous liquid rather solid, even if it is a controversial topic.
