Galvanized surface with visible spangle The size of crystallites in galvanized coatings is a visible and aesthetic feature, known as "spangle". Source: Internet
Such annealing also crystallizes BN, the size of the crystallites increasing with the annealing temperature. Source: Internet
Over time the cloudiness will disappear as the size of the crystallites increases, and eventually equilibrium will be reached in a process known as precipitate ageing. Source: Internet
Like the trunk portion of the body, the roots of the Vestimentiferan tubeworms are composed of chitin crystallites, which support and protect the tubeworm from predation and environmental stresses. Source: Internet
In common materials, crystallites are large enough that grain boundaries account for a small fraction of the material. Source: Internet
Since light reflects from the grain boundaries (boundaries between crystallites), larger crystals tend to be transparent, while the polycrystalline aggregates look like white powders. Source: Internet
