Abstract
BaCu₂O₂ (tetragonal, a = 5.722, c = 10.064 Å, space group I4₁/amd, Z=4) was identified by X-ray powder diffraction in plasma-sprayed YBaCuO coatings, together with Y₂O₃, YBa₂Cu₃O₇−δ, Y₂BaCuO₅ and BaCuO₂. In atmospheric plasma spraying, YBaCuO particles are melted at very high temperature and undergo a rapid solidification under low oxygen pressure which leads to the formation of a large amount of BaCu₂O₂. This interpretation also explains the experimental results of previous investigations in which the X-ray lines of BaCu₂O₂ had been ascribed to “an unknown BaO-CuO phase” or to “a simple cubic phase”
