“…4 Besides partial melting process, the Laser Zone Melting (LZM) method has been used as a suitable technique to texture this superconducting material in a planar configuration. Recently, Bi-2212 thick films were obtained on (1 0 0) MgO substrates by combining both, tape casting and LZM techniques.…”

“…In addition, the choice of the dispersant is very important because it should not contaminate the final product. To obtain an appropriated slurry with superconducting Bi-2212 powders, Glycerol Trioleate (Triolein) 4,5,9 or Sorbitan Trioleate 1,7,10,11 have been normally used as dispersant. In other cases, Terpineol has been added to the slurry.…”

“…In addition, Laser Zone Melting, combined with tape cast techniques have been used to fabricate Bi-2212 thick films on metallic and ceramic substrates, in particular, silver and MgO [24,25]. This is a good alternative to other usual techniques as dip coating [26], screen painting [27] or tape casting [28]. One of the advantages of laser zone melting is that the growth rates can reach high values.…”

Lasers are adequate tools in the processing and characterization of materials. The Applied Superconductivity group at the Aragón Materials Science Institute has been applying different laser techniques in the processing, machining and characterization of bulk high temperature superconductors for high power applications. Textured bulk Bi-2212 superconductors have been obtained using laser melting zone techniques. We have produced thin bars, monoliths and coatings on metallic and ceramic substrates. Ablation techniques have been used to machine the samples with the required shape for technological applications. And finally, optical techniques have been used as non-destructive experiments to detect the location of hot-spots and the positions where environmental degradation starts.

“…O xide superconductors such as YBa 2 Cu 3 O 7 1,2 and Bi–Sr–Ca–Cu–O 3,4 have been the subject of many experimental and theoretical studies since their discovery 5 . The YBa 2 Cu 3 O 7− x superconductor has many advantages over other high‐temperature oxide superconductors, namely, its superconducting transition above 77 K (the boiling point of liquid nitrogen) and large pinning force 6 .…”

The preparation of large‐scale YBa2Cu3O7−x superconductor samples was investigated. This method is based on plastic forming using a slurry consisting of YBa2Cu3O7−x particles and a sol solution made up of multimetallic hydroxide particles (YBa2Cu3(OH)x colloidal particles) and poly(vinyl) alcohol (PVA). The effects of adding PVA on the product, the crystallinity, and the superconducting properties of the sample were investigated. It was found that PVA acted as a protective colloid in the sol solution and stabilized YBa2Cu3(OH)x colloidal particles, and that the role of PVA changed from a thickener to a flocculant during drying so that the formability/workability of the green sheet sample was improved and large samples (about 80 mm × 80 mm × 3 mm) without large cracks were obtained after firing. The samples became superconducting at 91.5±0.5 K (Tcon) and the full transition temperature (Tcoff) was 88.5±1.5 K. The critical current density (Jc) of the sample prepared from the slurry containing 1 wt% PVA was 713±150 A/cm2 at 77 K. This Jc value was improved to 2300 A/cm2 by heat treatment at 773 K under an oxygen atmosphere.
