A reseach is carried out by using Alumina material type α-Al2O3 which has partical size
63μm doped with different percentage weight of MgO (0.1%,0.3%and0.5%) and by using dry
press method to prepare the samples ,A force press 50KN used and sintering to 1500o
C with
soaking time of 6 hours.
The physical properties were studied such as "Bulk density ,Porosity and water absorption
"also the mechanical properties such as (hardness,compressive strength ), the result shows that
the best ratio of maginsa(MgO) added to Alumina (Al2O3)is 0.5%and this worked to improve
Physical and mechanical properties .
