Any compound that contains either the O2- ion or oxygen with an oxidation state of -2, such as Li2O or H2O
- A metal-oxygen compound Most magnetic coatings are combinations of iron or other metal oxides, and the term has become a general one for the magnetic coating on tape or disk
A mineral compound characterized by the linkage of oxygen with one or more metallic elements, such a spinel, MgAl2O4
An oxide is a compound of oxygen and another chemical element. a substance which is produced when a substance is combined with oxygen (oxygène + acide ). Any of a large and important class of chemical compounds in which oxygen is combined with another element. Metal oxides contain a metal cation and the oxide anion (O2^-); they typically react with water to form bases or with acids to form salts. Oxides of nonmetallic elements are volatile compounds in which a covalent bond joins the oxygen and the nonmetal; they react with water to form acids or with bases to form salts. A few substances (e.g., aluminum, zinc) form amphoteric oxides, which form salts with both acids and bases. Certain organic compounds form oxides in which the oxygen is covalently bonded to an atom of nitrogen (amine oxides), phosphorus (phosphine oxides), or sulfur (sulfoxides) in the organic molecule. calcium oxide deuterium oxide nitric oxide nitrous oxide oxide mineral
A chemical compound, the combination of oxygen with a metal forming a ceramic; examples - aluminum oxide, zirconium oxide
One of several minerals containing negative oxygen ions bonded to one or more positive metallic ions
A chemical compound of oxygen with another element Hydrated (water-including) iron oxide is called rust; it does not cling tightly to the underlying metal, so the oxidation process is progressive and iron easily rusts away Aluminum oxide is a hard, transparent compound which clings tightly to the underlying metal and protects it against further oxidation
