Abstract We report the solution fabrication of a MgB2 coated conductor on a stainless steel substrate. The precursor solution of Mg(BH4)2 diethyl ether is initially synthesized by refluxing the milled mixture of NaBH4 and MgCl2 in diethyl ether. Then the Mg(BH4)2 diethyl ether is spin coated on a stainless steel substrate and annealed in Mg vapor, which yields a homogeneous MgB2 coated conductor. X−ray diffraction indicates that the grown MgB2 coated conductor is polycrystalline. It has a superconducting transition temperature of 34–37 K. The slope of the upper critical field HC increases with decreasing temperature, and the extrapolated value of HC(0) reaches ∼28 T. The critical current density estimated by the Bean model is JC (25 K, 0 T)∼106 A⋅cm−2. These parameters indicate that the solution method is potentially able to produce MgB2 coated conductors that can satisfy application purposes.
