摘要：
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 beta-CaSiO3 ceramics with 1 wt% B2O3 sintered at 1000 degrees 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 beta-CaSiO3 ceramics (30.2 MPa, 0.5 MPa m(1/2)). XRD analysis and SEM observation indicated that the main phase maintained to be beta-phase after sintering. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
