Abstract
A boron suspension in terpineol was applied to iron, titanium as well as to polycrystalline aluminium oxide, titanium dioxide and yttria doped zirconium dioxide substrates by screen printing. The samples were dried at 125 °C. The specimens were placed into a covered aluminium oxide crucible together with metallic magnesium. Conversion to magnesium diboride was carried out in an argon - hydrogen (6.5 vol-%) atmosphere under ambient pressure. Sintering temperature depended on the substrate chosen and varied between 750 °C and 950 °C. Dense and uniform MgB2-layers were obtained, showing transition temperatures of up to 38 K. Characterisation of the films was performed by X-ray diffraction, by scanning electron microscopy as well as by temperature - resistance measurements. Furthermore, technological applications of this technique will be discussed.
