Abstract
CeO2 ultrafine particles were prepared by solid-state reactions at room tem
perature. These particles were found to have very fine particle sizes (simi
lar to 3 nm) with a fluorite structure (a = 5.32 Angstrom). BET measurement
s showed that the surface area of the particles was 96.2 m(2)/g. The use of
two different precursors was found to affect the size of the CeO2, particl
es. We discuss the effect of calcination at different temperatures on the m
orphology, size, and BET surface area of CeO2, particles. A salt byproduct
coating prevented agglomeration of the CeO2, particles.
