Abstract
The present invention refers to a method for applying a smoothening layer on a band substrate for subsequent manufacturing a high temperature superconductor tape, wherein the method comprises the steps: (a) applying a liquid containing polysilazane on at least one side of the band substrate; and (b) heating the liquid containing polysilazane to a temperature≧450° C. for depositing a layer on the band substrate which comprises silicon oxynitride (SiNxOy, wherein 0≦x<0.6 and 1.0<y≦2.0), and/or silicon-carbon-oxynitride (SiCxNyOz, 2·y<x≦1.0, 0<y<0.2 and 1.0<z≦2.0).
