THE EFFECT OF TiO2 AS ADDITIVES ON PROPERTIES OF COMPOSITE MgO FOR BONE REPAIR

Abstract

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