Spray pyrolysis deposition of polycrystalline magnesia films and their use as buffer layers in Bi(Pb)-Sr-Ca-Cu-O/MgO/Al2O3 (or glass ceramics) structures

Journal Article


Abstract


  • The deposition of MgO films on Al2O3 and glass ceramic substrates by spray pyrolysis of a water-ethanol magnesium nitrate precursor solution has been studied. Dense polycrystalline films have been obtained by repeated pyrolysis at 300-350°C followed by annealing of the deposit in air at 970°C. It has been established that the finest grains obtained under these experimental conditions correspond to the films deposited on glass ceramic substrates. It has been shown that the MgO films can be useful buffer layers preventing the interaction between the above substrates and the BiSr-Ca-Cu-O films deposited on them by spray pyrolysis of nitrates.
