Description |
The effect of niobia and vanadia additions on the mechanical properties of alumina has been studied extensively and reported. It was observed that sintered density values of niobia doped samples increase with an increase in temperature. The optimum density has been obtained at 1500 degrees C, 500 min soaking with 0.5 wt% dopant concentration. The modulus of rupture values have been determined and correlated with a densification parameter. Vanadia doped samples have shown a different tendency in their sintered density values. In this case, the sintered density increases with an increase in temperature, but decreases with an increase in dopant concentration.
