Black amorphous form of carbon
Did you know?
Amorphous carbon is the name used for carbon that does not have any crystalline structure. As with all glassy materials, some short-range order can be observed, but there is no long-range pattern of atomic positions. While entirely amorphous carbon can be produced, most amorphous carbon actually contains microscopic crystals of graphite-like, or even diamond-like carbon. Coal and soot or carbon black are informally called amorphous carbon. However, they are product…
WebFeb 1, 2024 · Graphite is a naturally occurring form of carbon that is typically gray or black in color. It is one of the three allotropic forms of carbon, along with diamond and amorphous carbon. The color of graphite can vary depending on its purity and the presence of impurities.
