Graphite diamond carbon
Webdiamond crystals seem to be influenced by the presence of the a-C:H layer. The difference between the morphology of diamond crystals deposited on graphite samples and the ones deposited on silicon and SiAION samples can be attrib-uted to the local change in growth conditions induced by etching at the graphite surface. The high degree of renuclea WebGraphite is black or silver-black. Diamond comes in various colors. Behavior: Not volatile. Readily bonds with many elements and itself, forming millions of compounds. Uses: Essential component of all organic molecules, including nucleic acids, proteins, and carbohydrates. The C-14 isotope is used for carbon dating.
