The Preparation of Seeded Alumina from Alkoxide: (II) Sintering
The sintering behaviors of seeded alumina from alkoxide were studied. Room temp. desiccated powder exhibited better sintering behavior due to its packing ability and powder activity. $alpha$-Al2O3 2wt% seeded compacts sintered with 97.5%TD, 1~3${mu}{textrm}{m}$ diameters at 140$0^{circ}C$, 2hrs. Fe-nitrate doped compacts resulted in enhanced initial sintering behavior due to ionic effects of Fe3+ but failed to refined microstructure.
