Abstract

The article explores the possibility of obtaining a textured polycrystalline high-temperature superconducting ceramic coating on highly anisotropic structure. The synthesis of superconducting coating carried by the nominal compositions of amorphous precursor Bi1,7Pb0,3Sr2Ca(n-1)CunOy (n=3-9) which are obtained by quenching the melt under the influence of radiant heat and with a
pre-synthesized using high-temperature superconducting phases of the ceramic substrate, aluminum titanate (Al2TiO5). The study did not find that significant differences in the phase composition of the synthesized coatings. In all coatings the main phase is superconducting phase Bi1 Bi1,7Pb0,3Sr2Ca2Cu3Oy, wherein the superconducting phase present Bi1,7Pb0,3Sr2Ca(n-1)CunOy (n = 1, 2) having a low critical temperature bole. Texture of the particles of the superconducting coating was installed. Texturing of the coating is broken with increasing coating thickness of 120-140 mkm and above.
