Sintering of lime was carried out in the presence Of V2O5 by a single firing process. A pure limestone was crushed, mixed with 1, 2 and 4 wt.% V2O5, pelletised and fired between 1550 and 1650degreesC. The sintered lime was evaluated by bulk density, apparent porosity, microstructure, hydration resistance and hot modulus of rupture (HMOR) at 1300degreesC. Incorporation of V2O5 forms liquid phase with lime at elevated temperature and influences the densification process by liquid phase sintering. As a result bulk density of sinters improved and they become more hydration resistant due to the larger grain size of the lime phase. The hot strength increased up to a certain temperature followed by deterioration because of the pressure of higher amount of liquid phase. (C) 2004 Elsevier Ltd and Techna S.r.l.
