Özet

Effect of cerium oxide (CeO2) additive on the microstructure, mechanical and invitro bioactivity properties of a commercially synthetic hydroxyapatite (HA) was investigated. HA without CeO2 started to decompose at 1100 oC, but the decomposition temperature of the CeO2 added samples decreased up to 900 oC. Decomposition rate of the sintered samples increased as the sintering temperature reached to 1300 oC. It was about 5.8% for monolithic HA, and increased to 11.4% when the CeO2 additive to HA reached to 2.5 wt%. SEM images showed that an excessive grain growth as well as microcracks occured on the surface of monolithic HA when it was sintered at the temperatures than that of 1100 oC. The microcracks were also observed on the surface of HA-CeO2 composites, when they were sintered at 1300 oC. The composite of HA-0.5CeO2 sintered at 1100 oC possess the higher fracture toughness (Kıc) (2.510 ± 0.225 MPam1/2) and the higher compressive strength (152.73 ± 6.31 MPa) compared to other HA-CeO2 composites, and it's mechanical properties are higher than that of monolithic HA at about 2-3 times. In-vitro bioactivity test results showed that apatite layers on the surface of the samples were in the different morphologies.

Abstract

Effect of cerium oxide (CeO2) additive on the microstructure, mechanical and invitro bioactivity properties of a commercially synthetic hydroxyapatite (HA) was investigated. HA without CeO2 started to decompose at 1100 oC, but the decomposition temperature of the CeO2 added samples decreased up to 900 oC. Decomposition rate of the sintered samples increased as the sintering temperature reached to 1300 oC. It was about 5.8% for monolithic HA, and increased to 11.4% when the CeO2 additive to HA reached to 2.5 wt%. SEM images showed that an excessive grain growth as well as microcracks occured on the surface of monolithic HA when it was sintered at the temperatures than that of 1100 oC. The microcracks were also observed on the surface of HA-CeO2 composites, when they were sintered at 1300 oC. The composite of HA-0.5CeO2 sintered at 1100 oC possess the higher fracture toughness (Kıc) (2.510 ± 0.225 MPam1/2) and the higher compressive strength (152.73 ± 6.31 MPa) compared to other HA-CeO2 composites, and it's mechanical properties are higher than that of monolithic HA at about 2-3 times. In-vitro bioactivity test results showed that apatite layers on the surface of the samples were in the different morphologies.
