A series of Y1-xCaxBa2Cu3O7-y superconductor have been investigated. For x≤0.15,the Y3+ is replaced by Ca2+ in 123 phase and the solid solutions are formed. That leads to the slight increase of the lattice parameters of orthorhombic phase. When the contents of Ca increase, the contents of Cu3+ increase but their Tc decrease. It is considered that the properties of neighboring Cu(2)-O plane are affected, when the Y3+ is substituted by Ca2+ then it results in the Tc dropping. It is shown that the properties of Cu(2)-O plane are very important to superconductivity.
