An Efficient Combustion Process for Synthesis of YBa2Cu3O7
Abstract
A novel combustion process which saves time and energy for the synthesis of YBa2Cu3O7 superconductor is reported. The process involves ignition of metal nitrates—urea mixture which results in an intimate mixture of partially reacted oxides. After another combustion with ammonium nitrate and urea and subsequent heat treatment and oxygenation this gives single phase superconducting YBa2Cu3O7 powder.
