POLYCRYSTAL

A 'polycrystal' is a material that is made of many smaller and randomly oriented crystallites. ''Cf.'' monocrystal.
Almost all common metals, and many ceramics are polycrystalline. The crystallites are often referred to as grains.
Polycrystalline is a structure of a solid, such as brass, that when cooled form liquid crystals formed from different points within it. This creates many crystals within a structure, where these crystals meet is known as a grain boundary.
