Abstract :
Forsterite (Mg2SiO4) powder was synthesized using magnesium and talc with assistance of ball milling. Manganese doped forsterite was prepared at weight percentage of 0.05%, 0.1%, 0.2%, 0.5% and 1.0wt% by adding manganese oxide before ball milling. The undoped and manganese doped forsterite were sintered at temperature of 1000°C, 1100°C and 1200°C. The Vickers hardness, fracture toughness and Young’s modulus have improved when 0.2wt% of MnO2 was added in comparison with undoped forsterite. The recommended temperature to carry out the sintering process is 1100°C where improved mechanical properties were observed.
