Crystallite or grain
A crystallite is a small or even microscopic crystal which forms, for example, during the cooling of many materials. Crystallites are also referred to as grains. Bacillite is a type of crystallite. It is rodlike with parallel longulites. See more The orientation of crystallites can be random with no preferred direction, called random texture, or directed, possibly due to growth and processing conditions. While the structure of a (single) crystal is highly ordered and its See more • Lau, J. (2009). "Implementation of Two-Dimensional Polycrystalline Grains in Object Oriented Micromagnetic Framework".

WebJan 30, 2024 · Crystallite is a small crystal. It could be made of many many atoms/molecules that have undergone’faceting’ due to specific treatment. So crystallites are bigger than grains/particles. When one has a thin film or some other quasi-continuous form one needs to worry about average grain/particle size.
