Abstract

The effect of zinc on the stimulation of osteogenesis has become a major focus in research work on bone formation.Based on this fundamental work, a base HAP body (HAI) was reformulated by adding 10 wt% ZnO. The physical properties (i.e bulk density and porosiry), phase analysis (XRD) and surface fracture analysis (SEM) were determined affer sintering at five different temperatures (i.e 1150, 1200, 1250, 1300 and 1350°C). Addition of ZnO shows that the bulk density is decreased (2.30 - 2.70 g/cm3) porosity is increared (5.0 -27.0%) compared to a pure HAP (HAI) at these fie different temperatures. The XRD pattern of the HAP + ZnO (TIAIZ) indicated that the reaction of HAP and ZnO to form CaZn2 (PO4)2 occured at 1250°C.
