Other grains added to the twin form crystals that often appear symmetrically joined, sometimes in a starlike or crosslike shape.
WebThe following table organizes gemstones from highest to lowest refractive indices. Notes A double refraction of "none" means the stone is either isometric or amorphous. "Anomalous" means this singly refractive stone may show anomalous double refraction (ADR). Singly refractive gems with high refractive indices may show ADR. WebThis table summarizes the number and type of interstitial sites for simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed crystals. Interstitial Sites in the Basic Crystal Structures (SC, BCC, FCC, HCP) Check out my in-depth article about interstitial sites if you would like more diagrams, or proof of these values.
WebAll lattice planes and lattice directions are described by a mathematical description known as a Miller Index. This allows the specification, investigation, and discussion of specific planes and directions of a crystal. In the cubic lattice system, the direction [hkl] defines a vector direction normal to surface of a particular plane or facet.
