Monosized, spherical Y 2 O 3 was processed from raw commercial Y 2 O 3 by homogeneous precipitation in aqueous solution via urea decomposition. Dry‐pressed pellets of the synthesized and raw powders were sintered to 1500°, 1600°, and 1700°C for 7 to 720 min. Microstructural development was followed with scanning electron microscopy. The differences between sintering behavior of the two powders are discussed.
