What is Polycrystalline Structure - Material Properties

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, … See more The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure. A crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see … See more Rocks By volume and weight, the largest concentrations of crystals in the Earth are part of its solid bedrock. Crystals found in rocks typically range in size from a fraction of a millimetre to several centimetres across, although … See more Crystallization is the process of forming a crystalline structure from a fluid or from materials dissolved in a fluid. (More rarely, crystals may be deposited directly from gas; see See more In general, solids can be held together by various types of chemical bonds, such as metallic bonds, ionic bonds, covalent bonds, See more Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles. These shape … See more The same group of atoms can often solidify in many different ways. Polymorphism is the ability of a solid to exist in more than one crystal form.
