The modifications of the EPR spectra with the increasing of V2O5 content are explained supposing that these are the result of the superposition of two EPR signals, one with a well resolved hyperfine structure typical for isolated vanadyl ions and one consisting from a broad line without structure typical for clustered ions. The last species of ions is dominating in the glasses with x > 45 mol % V2O5.For the samples with x ⩾ 35 mol % V2O5 the reciprocal magnetic susceptibility follows the Curie behaviour.

However, for a long period of time, the principal interest in the electric conductivity of conducting powders was focused to its application on carbon brushes2, sintered electric contacts3 and electrochemical batteries4. The most prevailing sintering of metallic or ceramic parts was not affected by the electric conductivity of the raw powder. During the last years, however, electric heating methods, e.g. flash sintering, inductive sintering etc., have been developped and have partly been introduced into the sintering practice. One of the most urgent problems of these new procedures is the powder resistivity. Again, the most important problem of measuring powder resistivities is the separation of the contribution of powder particle cores and surfaces to the entire resistivity of the green powder pressing, before the heating process starts. A few considerations and experimental result will be given here below.</div>","PeriodicalId":18221,"journal":{"name":"Materials Chemistry","volume":"7 6","pages":"Pages 787-802"},"PeriodicalIF":0.0,"publicationDate":"1982-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0390-6035(82)90102-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72091527","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}
