Performance of oxide superconductors depends strongly on achieving efficient flux pinning leading to enhanced critical current densities from low to high fields. Methods of generating a uniform distribution of nano-metric particles or a network of nano-metric defects, in the superconducting matrix gain importance in this context. We report here a new process, which might be referred to as Nano-Dispersed Sol Casting (NDSC), for introducing nanoparticles, uniformly and without agglomeration, on the surface of Y2BaCuO5 (Y-211) particles. This powder can then be used to fabricate a preform of the desired shape and porosity for use in the Infiltration Growth (IG) process, to produce high current density components. As a specific example, we discuss here the example of CeO2 nanoparticles of similar to 30 nm diameter, and of CeO2 nano-rods of 300 nm length, which could be deposited by the above process uniformly and without agglomeration. Uniform deposition of individual particles, even when working with relatively high concentrations of the additive, up to 10% by weight, is demonstrated. The process consists of mixing stable Y-211 particle slurry with ceria sol of the required concentration, and then quickly freezing the Y-211 and ceria nanoparticle mixture in their fully dispersed state, through polymerization. The process is highly generic in nature; it can be used to dope other ceramic nanoparticles into the RE-123 superconductor. In fact, the NDSC process can be used to dope nanoparticles, in large concentrations if needed, in a matrix of a variety of ceramic powders, with possible advantages in the development of several products.
