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

摘要

Talc and magnesium oxide are used to prepare forsterite (Mg_2SiO_4) 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 (38 MPa·m~(1/2)) and Vickers micro-hardness (50 GPa) recorded with sintering temperature 1500°C with 1 hour holding time which makes forsterite suitable potential for biomedical application
