| Abstract | ||
| Magnesium oxide (MgO) is regarded as a biocompatible material. A composite material from MgO oxide prepared by mixing MgO powder with TiO2 (rutile phase) (2, 5, 10)Wt.% using powder metallurgy technique. It is used to be bioceramic material. The compressed samples were dried and sintered at (1200) ᵒC. porosity measurement showed that the porosity decreasing with increasing TiO2% . X-ray showed the presence of Mg2TiO4 in the composite structure of MgO with (5, 10)%TiO2 samples. The mechanical study showed an increasing in compressive strength, hardness, wear resistance and biodegradation resistance with increasing TiO2% content in the limit of used percentage. The prepared composite material didn’t present antibacterial activity while previous researches showed opposite result because of using nanoscale particle size of MgO. | ||
