Description

Samples of single phase 124 have been prepared at temperatures below 775C under 1 atm of O2 using freeze-dried nitrates and metal organic precursors. Below 700C the stable phase assemblage is Ba2Cu3O6-x + CuO + Y2O3. 124 samples formed by these methods have particle sizes as low as 0.3 μ, and are ideally suited for thick film preparation. In an attempt to increase the stability of this phase, the authors have also prepared various chemically substituted derivatives; including Ca for Y, which is known to increase Tc, and Ba for Sr. These results together with the properties of 124 thick films will be discussed
