초록
In the present study, phase pure forsterite was obtained in sintered bodies from powder mixtures that did not undergo a heat treatment process prior to sintering. This is contrary to the practice reported in the literature where the powder mixture is normally subjected to a heat treatment at about 1200 ο C prior to sintering process. The present results revealed that pure forsterite could be obtained after sintering the powder mixture above 1300 ο C. The study found that the mechanical properties of forsterite increased with increasing sintering temperature. A maximum Vickers hardness and fracture toughness of 7.68 GPa and 5.16 MPam1/2 were measured for samples sintered at 1500 ο C.
