Abstract

The development of ink synthesis for YBa2Cu3O7−δ (YBCO) coated conductors is discussed in detail. These chemical solution deposition (CSD) processes are for drop-on-demand ink-jet coating and ink-jet printing allowing non-vacuum formation of multi-layer superconducting patterns on metal substrates (with and without the aid of buffer layers).

Printing and substrate parameters that alter solid-liquid interface properties were investigated, and the sol-inks synthesised were aqueous and non-aqueous based therefore allowing variable chemical properties depending on what was required from the deposition process. The formation and the stability of the sol-inks has been studied and discussed, with the various synthesis steps and additives yielding the properties required to produce coatings.

Characterisation of the inks was by Differential Thermal Analysis and Thermal Gravimetry whilst characterisation of the coatings and products was by X-Ray Diffraction and Scanning Electron Microscopy. AC susceptibility was used to assess the superconductivity of the printed samples.
