#nanoHUB.org- Crystal Viewer Tool: visualizes Bravais lattices, Miller planes, and crystal structures of specific materials needed for many courses in materials, electronics and chemistry. Users can also view bulk #crystals for different materials as well as all 14 Bravais lattices. The main purpose of this #educational tool is to provide insight about the crystalline structure of various materials.
200 CTS CINNABAR SPECIMEN FROM CHINA [MGW1100 ] Cinnabar is generally found in a massive, granular or earthy form and is bright scarlet to brick-red in color. It occasionally occurs, however, in crystals with a non-metallic adamantine luster. Cinnabar has a rhombohedral bravais lattice, and belongs to the hexagonal crystal system, trigonal division.
