An example would be the dependence of Young's modulus on the direction of load. citation Anisotropy in polycrystalline materials can also be due to certain texture patterns often produced during manufacturing of the material. Source: Internet
For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure. Source: Internet
Anhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid. Source: Internet
Because of this, the powder diffraction method, which uses diffraction patterns of polycrystalline samples with a large number of crystals, plays an important role in structural determination. Source: Internet
By 2013, polycrystalline silicon production, used mostly in solar cells, was projected to reach 200,000 metric tons per year, while monocrystalline semiconductor grade silicon was expected to remain less than 50,000 tons/year. Source: Internet
