A photo of electrical steel (coating removed) showing polycrystalline structure

A polycrystal is a material that is made of many smaller crystallites with varying orientation. Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is specialty Steel tailored A crystallite is a domain of solid-state matter that has the same structure as a single Crystal. The variation in direction can be random (called random texture) or directed, possibly due to growth and processing conditions. Fiber texture is an example of the latter.

Cf. monocrystal. A single crystal, also called monocrystal, is a Crystalline Solid in which the Crystal lattice of the entire sample is continuous and unbroken

Almost all common metals, and many ceramics are polycrystalline. The M acro E xpansion T emplate A ttribute L anguage complements TAL, providing macros which allow the reuse of code across The word ceramic is derived from the Greek word κεραμικός ( keramikos) The crystallites are often referred to as grains. However, grains can themselves be polycrystalline^[1].

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.
