Abstract
The effects of plasma cycle and TiO2 doping on sintering kinetics duri ng plasma activated sintering (PAS) of gamma-Al2O3 have been studied i n the temperature range of 1473-1823 K. Multiple plasma cycle leads to higher densification. Also, TiO2 doping enhances the sintering kineti cs during PAS, In TiO2 doped specimens, near full density was obtained at 1673 K in less than 6 min using multiple plasma cycle. It is sugge sted that the dielectric properties of a material are critical for the success of the PAS process.
