Characterization of Forsterite Synthesized by Solid-State Reaction with Ball Milling Method

Talc and magnesium oxide are used to prepare forsterite (Mg2SiO4) powder by solid-state reaction with ball milling method. The samples were sintered at temperature 1200°C, 1300°C, 1400°C and 1500°C with four different holding time duration 2 hours, 1 hour and 1 minute with ramp rate of 10°C/min resp...

Summary:Talc and magnesium oxide are used to prepare forsterite (Mg2SiO4) powder by solid-state reaction with ball milling method. The samples were sintered at temperature 1200°C, 1300°C, 1400°C and 1500°C with four different holding time duration 2 hours, 1 hour and 1 minute with ramp rate of 10°C/min respectively via conventional pressureless sintering method. 3 hours ball milling is sufficient to form pure forsterite without any secondary phase. Highest values for fracture toughness (3.8 MPa.m1/2) and Vickers micro-hardness (5.0 GPa) recorded with sintering temperature 1500°C with 1 hour holding time which makes forsterite suitable potential for biomedical application.
