Isometric Crystal System Philosophy

2001-11-26  The Isometric crystal system characterizes itself by its three equivalent crystallographic axes perpendicular to each other. This means that undistorted crystals do not look elongated or flattened. They look like objects that could fit within a sphere. The Isometric System comprises six Crystal Classes.

Donald B Peck Crystallography: The Isometric System

Hexahedron: The hexahedron, or cube, is a special form that can be found in any crystal class of the isometric system. The ideal form has 6 square faces. Each face is perpendicular to a single crystallographic axis. The general symbol is {h00}: (100). (010}, (001). {1 00), etc. Octahedron: is a special form found in any class of the system. The

isometric system Definition & Facts Britannica

Isometric system, also called cubic system, one of the crystal systems to which a given crystalline solid can be assigned. Crystals in this system are referred to three mutually perpendicular axes of equal lengths. If the atoms or atom groups in the solid are represented by points and the points are connected, the resulting lattice will consist of an orderly stacking of blocks, or unit cells.

Amethyst Galleries THE ISOMETRIC SYSTEM

The lowest symmetry class in the isometric system is the Tetartoidal Class. It lacks any mirror planes or a center, but has the required 4 three fold axes in addition to 3 two fold axes that lie on the crystallographic axes. The tetartoid is a unique form and is a 12 sided form that peripherally resembles the

The vertical edges at the front and back, and the horizontal ones at the right, left, top and bottom of the pyritohedron are each parallel to an axis of 2-fold symmetry and normal to the other two 2-fold axes. (There are no axes of 4-fold symmetry in the pyritohedral class of the isometric system) and each is longer than any of the oblique edges.

Mineral Mineral Sulfides: This important class includes most of the ore minerals. The similar but rarer sulfarsenides are grouped here as well. Sulfide minerals consist of one or more metals combined with sulfur; sulfarsenides contain arsenic replacing some of the sulfur.

No crystal system even approaches a sphere's degree of symmetry, but the isometric system is often quickly recognizable because some of the forms and combinations of forms somewhat approach sphericity (or, at least, roundness), especially when the faces begin to be curved, due to the high degree of symmetry in the isometric system.

This is the lowest symmetry class of the isometric system and contains only three fold and two fold axes. Most gersdorffite has an unordered arsenic-sulfur structure and therefore belongs to the higher Diploidal symmetry class. Gersdorffite is very similar to a nickel antimony sulfide called ullmannite.
