Amine oxide Amine oxide An amine oxide, also known as amine-"N"-oxide and "N"-oxide, is a chemical compound that contains the functional group RN−O, an N−O coordinate covalent bond with three additional hydrogen and/or hydrocarbon side chains attached to N. Sometimes it is written as RN→O or, wrongly, as RN=O. In the strict sense, the term "amine oxide" applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary amines. Examples of amine oxides include pyridine-"N"-oxide, a water-soluble crystalline solid with melting point 62–67 °C, and "N"-methylmorpholine "N"-oxide, which is an oxidant. Amine oxides
Oxide dispersion-strengthened alloy ODS steel. This process seems simple but many parameters need to be carefully controlled to produce a well made alloy. Work by Leseigneur and coworkers has been done to carefully control some of these parameters in order to get more consistent and better microstructures in ODS steels. In this two step method the oxide is ball-milled for longer periods of time to ensure a homogeneous solid solution of the oxide in the metal matrix. Then the powder is annealed at higher temperatures to begin a controlled nucleation of the nano-oxide clusters. Finally the powder is again compressed and sintered to
