WebMar 14, 2024 · Another solid form of carbon known as graphite is the chemically stable form of carbon at normal temperature and pressure, although diamond nearly never transforms to it. Diamond has the highest hardness and thermal conductivity of any natural substance, characteristics that make it ideal for cutting and polishing equipment in the industry. WebGraphite is dark gray to black, opaque, and very soft (with a hardness of 1 1/2 on the Mohs scale ), while diamond may be colourless and transparent and is the hardest naturally occurring substance. Graphite has a greasy …
WebIt is a strong, rigid three-dimensional structure that results in an infinite network of atoms. This accounts for diamond’s hardness, extraordinary strength and durability and gives diamond a higher density than graphite (3.514 grams per cubic centimeter).
