Abstract
The effect of heating rate on the sintering of agglomerated NaNbO3 powders, processed by the polymeric precursors method, was studied. The results sho wed that the presence of agglomerated powder leads to a heterogeneous micro structure, with bimodal grain size distribution, after sintering. Using a h igh heating rate, the sintering of agglomerated particles was inhibits, lea ding to a homogeneous microstructure, with single grain size distribution. (C) 1998 Kluwer Academic Publishers.
