文摘

CaSiO₃ ceramics were fabricated with and without B₂O₃ addition by pressureless sintering. The results showed that B₂O₃ can be successfully used as sintering additive through liquid sintering. The β-CaSiO₃ ceramics with 1 wt% B₂O₃ sintered at 1000 °C revealed flexural strength and fracture toughness of 168.4 MPa and 2.1 MPa m^1/2 respectively, both of which were much higher than those of pure β-CaSiO₃ ceramics (30.2 MPa, 0.5 MPa m^1/2). XRD analysis and SEM observation indicated that the main phase maintained to be β-phase after sintering.
