Bioengineered and biocompatible Zirconia based ceramics for tissue engineering applications

This research work explains the densification behavior, mechanical properties, and microstructure of high-purity titanium oxide (TiO2) and tricalcium phosphate (TCP)-doped Y-TZP where different weight percentage of TiO2 varied from 0 to 10wt% and a fixed percentage of 15wt% for tricalcium phosphate...

This research work explains the densification behavior, mechanical properties, and microstructure of high-purity titanium oxide (TiO2) and tricalcium phosphate (TCP)-doped Y-TZP where different weight percentage of TiO2 varied from 0 to 10wt% and a fixed percentage of 15wt% for tricalcium phosphate were used in this research work. The preparation of the samples was done by uniaxially pressing the samples at 200MPa into circular discs and rectangular bars and pressureless-sintered at temperatures ranging between 1200˚C to 1400˚C for 90 minutes holding time. The microstructure of the samples was characterized using the scanning electron microscope (SEM).

The results had shown significant improvement in terms of mechanical properties with the addition of dopants to the pure Y-TZP powder. In addition to that, the dopants have reinforced and toughened the samples. The results obtained for the mechanical properties of the TiO2 and TCP-doped Y-TZP ceramics were 4.89Mgm-3 and 10.67GPa for density, and Vickers hardness, respectively, for the composition of 10wt% TiO2/15wt% TCP and 75wt% ZrO3 sintered at 1400˚C with 90 minutes holding time. © BEIESP. 2020-02-03T03:29:58Z 2020-02-03T03:29:58Z 2019-05 Article http://dspace.uniten.edu.my/jspui/handle/123456789/13042 en International Journal Of Innovative Technology And Exploring Engineering (Ijitee)
