Alumina is a ceramic substance with high melting temperatures and good mechanical qualities that is utilised in a variety of applications, including furnace components, electronics substrates, cutting tools, and abrasion and corrosion resistance. The main goal of this research is to figure out what sintering conditions are needed to get alumina powder to a near-theoretical density. This paper investigated the effect of sintering temperature on sintered density. By altering the sintering (soaking) time, the influence of sintering time on densification was also investigated, and it was discovered that densification increases as sintering time increases. Even after 14 hours of sintering, full densification was not achieved, despite the fact that density increased with soaking time. Alumina samples were sintered using 1 percent Magnesium Oxide (MgO) by weight to minimise the sintering time to a minimum. The amount of time needed to densify alumina powder with MgO addition to a near-theoretical value was calculated. The sintered samples' microstructures were developed, and the sintered product's hardness was assessed. MgO was found to be an excellent sintering aid for sintering alumina in this investigation.
