Cordierite-TiO2 composite (5-20 wt.%) ceramics for various stoichiometric compositions were synthesised using conventional techniques with standard raw materials. The green composite ceramic samples obtained were dried at 100 C for 12 h, followed by pre-sintering at 800 C for 3 h. The powders were dry milled for 2 h and then compacted at 240 MPa to form pellets. The sample pellets were sintered at temperatures in the range of 600-1300 C for 3 h. The study of the different phases of the samples was performed using X-ray diffraction. The poor mechanical properties of cordierite have attracted the use of TiO2 as a dopant. A study on the influence of TiO2 addition to flexural strength, fracture toughness, hardness, bulk density and thermal expansion was performed. Vickers hardness value of the cordierite-TiO2 composites of 6.46 GPa is higher than other compositions of cordierite. The cordierite-TiO2 exhibited a fracture toughness of 3.28 MPa m1/2. The flexural strength of the cordierite-TiO2 was 158.47 MPa. The effect of thermal expansion was very low in the cordierite-TiO2. Studies using X-ray diffraction and scanning electron microscope imaging on samples sintered at 1300 C confirmed the presence of cordierite, along with small amounts of rutile and cristobalite. © 2013 Brazilian Metallurgical, Materials and Mining Association.
