Monocrystalline silicon has two isomorphous, crystalline and amorphous forms. Crystalline silicon is further divided into single crystal silicon and polycrystalline silicon, both of which have a diamond lattice. The crystal is hard and brittle, has a metallic luster, and is electrically conductive, b

Bismuth (III) oxide is an important compound of Bismuth, Bismuth oxide has two kinds of crystal structure: Alpha type and Beta type. Compared with beta Bismuth oxide, alpha Bismuth oxide is more stable in high temperature and has more common use of electronic materials, thermistor, glass coloring, v
