Method for producing silver coated superconducting ceramic powder
Description
This patent describes a process for coating superconducting ceramic powders with silver metal. It comprises: mixing AgNO3 with superconducting ceramic powder; heating the AgNO3 superconducting ceramic powder mixture at a temperature above the melting point of AgNO3 but below the decomposition temperature of AgNO3 until AgNO3 melts and forms a uniform coating over the surfaces of the superconducting ceramic particles; and heating the molten AgNO3-coated superconducting ceramic powder at a temperature from the decomposition temperature of AGNO3 to 50 degrees C. below the melting point of the superconducting ceramic powder until the AgNO3 decomposes to form a thin, uniform coating of silver metal over the surfaces of the superconducting ceramic powder particles
