ROENTGENO-ELECTRONIC INVESTIGATION OF THE METALOXIDE CERAMET OF THE BASE OF COPPER AND LANTHANOIDES, YTTRIUM, BISMUTH, TALLIUM

Abstract

The object of investigation: the metallooxide ceramet on the base of copper and lanthanoides (La, Eu), yttrium, bismuth, tallium, the original metals and its oxides. The purpose of the work: the investigation of the common laws of fformation of electronic structure, properties and character of chemical bond of the metallooxide ceramet on the base of copper and lanthanoides, yttrium, bismuth, tallium, using the parameters of its reontgenoelectronical spectres. The laws of formation of the electronic structure, properties and character of chemical bond of the metallooxide ceramet on the base of copper and lanthanoides, yttrium, bismuth, tallium have been established. With use of the sensitivity factors to be measured in the work, the influence of the air atmosphere on the surface of films of the high-temperature superconductor YBa*002Cu*003O*007*00-*00 *00d*00e*00l*00t*00a*00 has been studied with a view to determining the conditions of its storage, transportation and investigation of the degree of its degradation depending on the time of staying in the airAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
