Synthesis of YBa2Cu3O7-x powder by autoignition of citrate-nitrate gel
TL;DR: In this paper, a simple and convenient method for the synthesis of YBa2Cu3O7−x powder is described, which involves autoignition of a citrate-nitrate gel resulting from a thermally induced oxidation-reduction reaction to yield an ash that upon calcination produces the desired compound.
