Tetragonal crystal system - Wikipedia

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).

Magnetocrystalline anisotropy - Wikipedia

Higher order constants, in particular conditions, may lead to first order magnetization processes FOMP.. Tetragonal and rhombohedral systems. The energy density for a tetragonal crystal is / = ⁡ + ⁡ + ⁡ ⁡. Note that the K 3 term, the one that determines the basal plane anisotropy, is fourth order (same as the K 2 term). The definition of K 3 may vary by a constant multiple between ...

Hexagonal crystal family - Wikipedia

Jul 21, 2009  The hexagonal crystal family consists of two crystal systems: trigonal and hexagonal.A crystal system is a set of point groups in which the point groups themselves and their corresponding space groups are assigned to a lattice system (see table in Crystal system#Crystal classes).. The trigonal crystal system consists of the 5 point groups that have a single three-fold rotation axis, which ...

Barium titanate - Wikipedia

The solid exists in one of four polymorphs depending on temperature. From high to low temperature, these crystal symmetries of the four polymorphs are cubic, tetragonal, orthorhombic and rhombohedral crystal structure.All of these phases exhibit the ferroelectric effect apart from the cubic phase. The high temperature cubic phase is easiest to describe, as it consists of regular corner-sharing ...

Zircon - Wikipedia

Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates, and it is a source of the metal zirconium.Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4.A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.Zircon forms in silicate ...

Cristobalite - Wikipedia

A tetragonal form of cristobalite (P4 1 2 1 2, No. 92, Pearson symbol tP12) occurs on cooling below about 250 °C at ambient pressure and is related to the cubic form by a static tilting of the silica tetrahedra in the framework.

Body-Centered Tetragonal Crystal System - an overview ...

The structure of a steel quenched to form martensite is highly unstable. One reason for the instability is the supersaturation of carbon atoms in the body-centered-tetragonal (bct) crystal lattice of martensite (Krauss, 1980). Normally case-hardened workpieces in the first stage are tempered at temperatures between 150°C and 200°C.
