A study on the effects of sintering temperature on the densification of alumina / Mohd Muslim Md. Isa

Aluminium Oxide (Al2O3), also known as alumina is an advanced ceramic material with a wide range of applications. Therefore, it is important to analyze and understand the impact of processing on its properties. In this project, alumina powder was mixed with a small amount of magnesium oxide (MgO) al...
