Influences of heating processes on properties and microstructure of porous CeO2 beads as a surrogate for nuclear fuels fabricated by a microfluidic sol-gel process

This study concerns the effect of heating processes on properties and microstructure of the fuel particles. The uniform gel precursor beads were synthesized by a microfluidic sol-gel process and then the porous CeO2 microspheres, as a surrogate for the ceramic nuclear fuel particles, were obtained by heating treatment of the gel precursors.
