Abstract

The present research aims to synthesize the HA/YSZ composite and to formulate HA/YSZ-GIC for improving the fluoride release of the set cement. Experiments were performed by mixture design (MD) method, and data analysis was carried out by mini- tab 14 software. The results showed that the combination of 25.891wt.% HA, 70.246wt.% ZrO2 and 3.86wt.% Y2O3 has desirable fluoride release profile. Combination of HA/YSZ-GIC in the optimized formulation improved the fluoride release from 7 ppm to 18 ppm after immesrsion for 56 days.
