Description

The effect of niobium oxide addition on the alumina-zirconia thermal diffusivity was investigated from 1000 C to 10000 C by the laser flash method. It was observed that 4 to 6% addition of niobium oxide increases the thermal diffusivity when samples were sintered at 14500 C. This effect was due to elimination of porosity by formation of liquid please above 14200 C in the Al2 O3 - Nb2 O5 system. (author). 7 refs., 3 figs
