摘要：
The effect vapors of the simplest cyclic hydrocarbons have on the structure of YBa2Cu3Oy (123) with high (& x443; = 6.96) and low (& x443; = 6.3) oxygen concentrations at low temperatures (200-300 degrees C) is studied. It is found that the hydration of 123 proceeds during low-temperature treatment in vapors of these hydrocarbons. The planar packing defects form in YBa2Cu3Oy in optimum amounts along with second-phase inclusions formation as a result of the reduction of copper. The formed centers of pinning can improve the critical properties of HTSC materials in strong magnetic fields.
