We show that a homogeneous single-phase mixed oxide is obtained by blending and sintering commercial UO2 and nanocrystalline PuO2 powder; whereas, under the same conditions, conventional PuO2 powder obtained from oxalate precipitation and composed of platelets, yields two-phase mixed oxide. The use of nanometric PuO2 results in a larger final grain size.
