Abstract
Superconductive thick film of BPSCCO was formed on MgO substrate by gas deposition using fine powder of BPSCCO having diameter less than 1μm. After heat treatment at 770°C for 10hr in air atmosphere by use of electric furnace, Tc(end) was found 105K.
In this study, as deposited BPSCCO thick film, which was moved at the speed of 1mm/min, was heated by infrared heating spot. After heating the surface of MgO substrate at the temperature of 920°C by infrared spot, Tc(end) of BPSCCO thick film was found 85K.
It is desired to select more suitable heating condition. This heat treatment is useful for continuous manufacturing process of long superconductive thick film.
