Material properties of diamondDiamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence). Diamond is the hardest naturally occurring material known. Yet, due to important structural brittleness, bulk diamond's toughness is only fair to good.
Non-ferrous metalIn metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), non-magnetic properties or resistance to corrosion (e.g. zinc). Some non-ferrous materials are also used in the iron and steel industries.
Oxyde de carboneUn oxyde de carbone est un composé chimique constitué d'une combinaison d'atomes de carbone et d'oxygène uniquement. Les plus simples et les plus communs des oxydes de carbone sont le monoxyde de carbone, CO, et le dioxyde de carbone, . Beaucoup d'autres oxydes de carbone stables, métastables ou hypothétiques sont connus mais sont rarement rencontrés comme le suboxyde de carbone , ou l'anhydride mellitique , voire très rarement, comme le monoxyde de tricarbone , ou l'évanescent tétroxyde de carbone .
