Download or read book Passivity of Metals and Semiconductors written by Michel Froment and published by Elsevier. This book was released on 2013-09-03 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passivity of Metals and Semiconductors covers the proceedings of the Fifth International Symposium on Passivity, held in Bombannes, France on May30 - June3, 1983. The said symposium is concerned with passivity of metallic materials, localized corrosion, experimental techniques, and classical techniques such as optical techniques and electron spectroscopy. The book is divided into five sections. Section I deals with the concepts involved in the composition-transport phenomena and covers topics such as the transport of oxygen and water in oxide layers; the kinetics of oxidation of silicon; and the oxidation rate laws of metals that form nonstoichiometric oxides. Section II covers related techniques and their specific applications such as study of passivity of iron by in situ methods; optical methods in the study of passive films; and the analysis of multiple layer surface films by modulated reflection spectroscopy. Section III tackles amorphous metals - their passivity, their depassivation and repassivation in localized corrosion, and a comparison of models for localized breakdown of passivity. Part IV discusses the photoelectrochemistry of semiconductors; Part V tackles passivation and localized corrosion of stainless steels. The text is recommended for organic chemists, metallurgists, and engineers who would like to know more about the passivity of metals and their applications in different fields.

Download or read book Anodic dissolution of uo2 in slightly alkaline sodium perchlorate solutions written by S. Sunder and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anodic dissolution of uo2 has been studied in aqueous sodium perchlorate solutions at ph approximately 9.5. under potentiostatic conditions two distinct regions of oxidation/dissolution behaviour were observed. in the potential (e) range 0.100 v approximately e approximately 0.350 v (vs. sce) currents decayed continuously with time due to the formation of oxidized surface films which gradually blocked further oxidation of the electrode. steady-state currents were not achieved even after 24 hours. on the basis of anodic and cathodic charges (q sub(a), q sub(c) respectively) obtained by integration of the anodic current-time plots (q sub(a)) and cathodic potential scans to reduce accumulated oxidized surface films (q sub(c)), it was shown that approximately 90% of the anodic oxidation current went to produce these films. for e approximately 0.350 v, steady-state currrents were obtained and measurements of q sub(a) and q sub(c) showed the majority of the current went to produce soluble species. the film blocking anodic dissolution appeared to be either uo sub(2.67) or, more probably, uo3 middle dot 2h2o located primarily at grain boundaries. it is proposed that, at the higher potentials, rapid oxidation and dissolution followed by the hydrolysis of dissolved uranyl species leads to the development of acidic conditions in the grain boundaries. at these lower ph values the uo3 middle dot 2h2o is soluble and therefore does not accumulate. alternatively, if this oxide has been formed by prior oxidation at a lower potential, the formation of protons on oxidizing at e > approximately 0.350v causes its redissolution, allowing the current to rise to a steady-state value. on the basis of tafel slopes, an attempt was made to demonstrate that the observed behaviour was consistent with dissolution under acidic conditions. this analysis was only partially successful.

Download or read book Radioactive Waste Forms for the Future written by Werner Lutze and published by North Holland. This book was released on 1988 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a compilation of important information on the full range of radioactive waste forms that have been developed, or at least suggested, for the incorporation of high-level nuclear waste. Many of the results were published in the ''gray literature'' of final reports of national laboratories or in various, generally less available, proceedings volumes. This is the first publication to draw information on nuclear waste forms for high-level wastes together into a single volume. Although borosilicate glass has become the standard waste form, additional research in this compound is still necessary. With improved technology (particularly processing technologies) and with a more detailed knowledge of repository conditions, glasses and second generation waste forms with improved performance properties can be developed. Sustained research programs on nuclear waste form development will yield results that can only add to public confidence and the final, safe disposal of nuclear waste. The aim of this volume is to provide a 'spring board' for these future research efforts. A detailed presentation is given on the properties and performance of non-crystalline waste forms (borosilicate glass, sintered glass, and lead-iron phosphate glass), and crystalline waste forms (Synroc, tailored ceramics, TiO 2 - ceramic matrix, glass-ceramics and FUETAP concrete). A chapter on Novel Waste Forms reviews a number of methods that warrant further development because of their potential superior performance and unique applications. The final chapter includes a tabulated comparison of important waste form properties and an extended discussion on the corrosion process and radiation damage effects for each waste form. Of particular interest is a performance assessment of nuclear waste borosilicate glass and the crystalline ceramic Synroc. This is the first detailed attempt to compare these two important waste forms on the basis of their materials properties. The discussion emphasizes the difficulties in making such a comparison and details the types of data that are required. Each chapter has been written by an expert and includes a current compilation of waste form properties with an extensive list of references. This volume will provide a stimulus for future research as well as useful reference material for scientists working in the field of nuclear waste disposal and materials science.

Download or read book The Kinetics of Dissolution of Beta-uranium Trioxide in Acid and Carbonate Solutions. Part 2 - Carbonate Solutions written by and published by . This book was released on 1976 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The kinetics of dissolution of beta-uranium trioxide in carbonate solutions have been studied as functions of stirring rate, carbonate concentration, hydrogen ion concentration, various cations in solutions and temperature. The salient features are that the dissolution rates were: (i) Independent of stirring rate. (ii) Dependent on the 1.0 order of the carbonate concentration. (iii) Linearly decreasing functions of pH. (iv) Inhibited by cations. The rate decreased in the order Na+>NH4+>Cs+>K+. (v) Arrhenius functions of temperature, with an activation energy of about 15 kcal per mol. The observed kinetic data has been rationalised in terms of a Charge Transfer mechanism, namely, the transfer of carbonatouranyl species and protonated oxide species across the electrochemical potential barrier at the solid-solution phase boundary is the rate-determining step during the dissolution reaction.
