As the quality of the coke available for production of anodes is changing, future production will rely on cokes that are more isotropic with higher impurity levels than traditional raw materials. The purpose of this work was to improve the understanding of the electrochemical reactivity of different cokes. An-ode:electrolyte wetting is a key factor towards determining electrochemical reactivity, which in turn is affected by anode properties, type of coke and polarization. Pilot anodes were fabricated from single source cokes; one anisotropic coke low in impurities, and one isotropic coke with significantly higher impurity levels. Electrochemical characterisation included chronopotentiometry, cyclic voltammetry and impedance spectroscopy. Wetting properties were studied on both unpolarised and polarised samples by a dedicated wetting apparatus, and indirectly by computed tomography (CT) images of frozen electrolyte films.","PeriodicalId":18036,"journal":{"name":"Light Metals","volume":"101 1","pages":"865-870"},"PeriodicalIF":0.0,"publicationDate":"2016-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80868816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, the mechanism of so-called “poisoning” effect was investigated by advanced analytical microscopy, including Cs-corrected high resolution STEM. For the first time, adsorption of Zr atoms was observed in a mono-layer on {0001} surface of TiB2. Significantly, atomic resolution STEM Z-contrast imaging revealed that the brightness of atomic columns in the monolayer varied periodically when viewing in ([10bar 10]) direction, indicating that the adsorbed Zr atoms in the layer were ordered in 2D. Deviation by 8 degrees from the well define orientation relationship, (0001)TiB2 8deg ~ (111)Al, and ({[11bar 20]_{TiB2}}parallel {[0bar 11]_{A1}}), was observed. The effect of Zr atom adsorption at the interface on mechanism of heterogeneous nucleation was discussed.","PeriodicalId":18036,"journal":{"name":"Light Metals","volume":"1 1","pages":"725-729"},"PeriodicalIF":0.0,"publicationDate":"2016-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91263720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
