Intriguing work has been performed showing the effects of electric fields on the sintering of ceramics. The objective of this work was to investigate the effect of electric fields on the sintering and microstructure evolution of nanoparticles. Nanometric powders of MgAl2O4 were synthesized via the Pechini and co-precipitation method. Sintering in air at 1300C resulted in extremely differing final states when comparing the two powders. Additionally, pellets of were sintered with and without DC electric field of 50,000V/m. Interesting grain growth behavior and pore structures were observed due to application of the applied electric field when compared to no field. Sintered microstructures were analyzed using electron microscopy techniques while in-situ TEM techniques are employed to investigate electric field effects on individual and small Ni/NiO particle agglomerates.
