Preparation of YBCO platelets and films by MOD and microwave heating
- Univ. of Turin, Torino (Italy)
Metal Organic Deposition (MOD) technique, which represents a flexible method for obtaining both platelets and films of YBCO, is based on baking, pyrolyzing and annealing stages of neodecanoates solutions. The annealing step is generally very long. The whole annealing stage can be simply substituted by a heat treatment (about 1 h) in a commercial microwave (MW) oven, followed by a 15 min. annealing at 900 C in a resistive furnace without oxygenation. With this process, YBCO platelets, films and wires were obtained starting from powders prepared by MO (Metal-Oxide). XRD patterns are indicative of a strong texturing by the evidence of (003) and (005) lines. By the same technique, YBCO films were prepared by spray deposition in Al{sub 2}O{sub 3} for a total thickness of about 5 {micro}m, each spray step, of 1 {micro}m, was followed by 5 min pyrolysis at 500 C and 1 h MW annealing. The MW technique was also used for preparation of quartz and ceramic fibers covered by YBCO.
