This paper presents the results of investigations of a state-of-the art hightemperature ceramic superconducting tape of the SF 12050 series. The study focuses on the current and voltage characteristics, examination of the microstructure and analysis of the chemical composition in superconducting tapes of the SF series. In order to measure the current parameters, a measuring system was designed to investigate sections of the tapes at the temperature of liquid nitrogen. The system is powered with a direct current of parameters I = 0÷580 A and U = 0÷8 V. Measurements of the critical current were taken by means of determination of the decline in voltage along the measurement section for the tape with an accuracy of 1nV. Analysis of the chemical composition was carried out by using a scanning microscope which features a chemical composition microanalyser EDX. The paper presents microscopic images which are a result of the examination of the structures by means of a light microscope and scanning microscope. The method of preparation of the superconducting tapes for soldering and the method the selecting of solder were also presented.
