In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).

tetragonal system, one of the structural categories to which crystalline solids can be assigned. Crystals in this system are referred to three mutually perpendicular axes, two of which are equal in length.

2018年11月8日 · There are some 300 minerals that crystallize in the Tetragonal System (2018). Approximately 175, more than half, are classified in the Ditetragonal Dipyramidal Class. About 40 minerals crystallize in the Tetragonal Scalenohedral Class; and fewer than to …

2022年11月24日 · There are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic. The crystal systems are listed in order of decreasing symmetry.

In the tetragonal system, like the orthorhombic system, the conventional unit cell is a parallelepiped, but two sides are equal, so that $a = b$ and $c \ne a$, while $\alpha = \beta = \gamma = \pi/2$, making this a special case of the orthorhombic system.

A tetragonal system has simple and body-centred tetragonal cells, and the Bravais lattice follows the given relation: a, b are equal but not equal to c. α, β and γ equals to 90 degree. Tetragonal crystal system examples are for the simple cells and body-centred cells structures.

The meaning of TETRAGONAL is of, relating to, or characteristic of the tetragonal system.

2018年5月8日 · tetragonal One of the seven crystal systems, with two sets of edges of the same length and a third which is either longer or shorter than the other two. The lattice may be referred to three crystallographic axes, a1, a2, and c (or x, y, and z) where a1 and a2 (or x and y) are equal, and c (or z) may be longer or shorter.

Like the cubic system, the tetragonal system has three axes that all meet at 90 degrees. It differs from the isometric system in that the C axis is longer than the A and B axis which are the same length. This makes it’s for a rectangular prism.

Tetragonal refers to a specific type of crystal system characterized by a unit cell that has two equal axes and one axis that is different in length. This structure plays an important role in determining the physical properties of materials, such as …
