Kinetics of Cr2O3 growth during the oxidation of Cr(110)doi:10.1209/epl/i1997-00158-3Andreas StierleHartmut Zabel
Point defects play an important role in regulating the effectiveness and establishing the limits of Cr2O3 corrosion protection, so significant theoretical, experimental, and modelling efforts have been undertaken to understand the nature of point defects that control oxidation and their diffusion ...
Assign oxidation numbers to each of the elements in MnO2.Assign an oxidation number to the metal in the following compounds. a. Bi2O3 b. UF6 c. V2O5Assign oxidation numbers to each of the atoms: O, C, and S in OCS.Assign oxidation numbers to all elements in the compound Fe2...
解析 CThe only correct answer is CA is not correc because the xidatio number of Cr is +3 and Mn is +2B is not correc because the xidatio number of Cr is +6 and Ti is+3D is not correc because the xidatio numbe of Cr is +6 and Mn is +7 ...
Structure and properties of TiO[sub 2] surfaces: a brief review. The growth of a large number of different metal overlayers has been studied on TiO[SUB2](110). Some of these studies have been instrumental in further... Diebold,U. - 《Applied Physics A Materials Science & Processing》 被...
The oxidation of CH3Cl in air using a commercially available Cr2O3 catalyst was studied in a packed-bed, isothermal reactor in the temperature range of 340-470掳C and at I atm. Reaction rates were independent of the concentration of oxygen for CH3Cl partial pressures below 0.043 atm. A ...
Effect of oxide grain structure on the high-temperature oxidation of Cr Cr was oxidized in 1 aim O 2 at 980, 1090, and 1200掳C. Electropolished Cr and some orientations of etched Cr oxidize rapidly and develop compressive str... D Caplan,GI Sproule - 《Oxidation of Metals》 被引量: ...
In the present work, the reoxidation of Al-killed molten steel from the magnesia-chromite refractory was investigated. Firstly, the composition and the phases of magnesia-chromite bricks from three different steelmaking shops were analyzed. Secondly, the magnesia-chromite bricks were immersed in Al-...
Although the metal region could also affect the ASR results due to its thicker thickness (∼ 2 mm) compared to the oxide layer (∼ 4 μm), it is neglected in this study. This assumption is based on the significantly higher resistivities of Cr2O3 [27], [28], [29] and Mn-...
