kristallisüsteemi

The term "kristallisüsteemi" refers to a crystal system, which is a classification of crystals based on their internal symmetry. There are seven distinct crystal systems, each defined by the lengths and angles of its unit cell axes. These systems are cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, and trigonal. The cubic system is the most symmetrical, with all axes equal in length and at right angles to each other. The triclinic system is the least symmetrical, with axes of different lengths and angles. The crystal system dictates the possible external forms a crystal can take, such as cubes, prisms, and pyramids. Understanding the crystal system is fundamental in crystallography for identifying and characterizing minerals and other crystalline materials. It influences physical properties like optical behavior and cleavage. Each system can be further subdivided into Bravais lattices, which describe the specific arrangement of atoms within the unit cell. The seven crystal systems provide a universal framework for describing the geometric arrangement of atoms in solid materials, forming the basis of solid-state physics and materials science.
