Abstract

The paper presents the study of the particle size distribution, surface area and their effect
on sintering of alumina (Al2O3) using additives such as magnesium oxide (MgO) and silica (SiO2),
so that the samples could be sintered to high relative density (~ 97.43 %) with controlled grain
growth. However, the use of MgO along with SiO2 on Al2O3 produced the powder compacts
having high Green density, sintered density with minimum porosity to achieve high dielectric
strength ceramic material, so that material can be used for high-voltage insulator applications.
