Spray pyrolysis was used to fabricate TiO2-Ag composite powders for application in oxide barrier between filaments of superconducting multifilamentary tapes. The powders were prepared from an aqueous solution of TiO2 sol and AgNO3. SEM and TEM observations revealed that the average size of the synthesized powder was less than 1 μm and consisted of well-dispersed fine primary particles of TiO2 and Ag. It was clearly observed that the microstructure of the particles was altered by conditions of heat treatment.
