Summary:The effects of sepiolite mineral nanofiber on strength and toughness of ceramics were investigated by bone china with addition of sepiolite mineral nanofiber. The flexural strength and fracture toughness were tested by three point bending method and single edge notched beam (SENB) method, and the microstructure of the ceramics was studied by scanning electron microscopy (SEM), X-ray diffraction (XRD) and optical microscopy. The results indicated that the structure pattern of sepiolite mineral nanofiber became much shorter and thicker after calcinations. Proper addition of sepiolite mineral nanofiber would increase the strength and toughness of bone china. The sepiolite mineral nanofiber can yield the bone china with fracture toughness and flexural strength values as high as 5.65 MPa·m1/2 and 112.66 MPa to 5.87 MPa·m1/2 and 118.90 MPa, mainly due to crack bridging, crack deflection and pullout by sepiolite mineral nanofiber.
