摘要：
A method for electrochemical synthesis of a superconducting boron compound MgB2 which comprises the steps of preparing a powder mixture of magnesium chloride, sodium chloride, potassium chloride and magnesium borate, drying the mixture by electrical heating at a temperature of 400° C. or below under an inert gas atmosphere, and further heating the mixture electrically at a temperature of 400° C. or above so that it is melted and undergoes chemical reaction.
