The sintered composites (700–1000 1C/30 min) with relative densities between 95% and 98%, showed β-podumene,TiO 2 and L i2 TiSiO 5 as main crystalline phases. The maximum bending strength (235 7 84 MPa) was achieved for composites with 40% TiO 2 sintered at 1000 1C/30 min. The coefficient of thermal expansion increased linearly with the concentration of TiO 2 , i.e., 3.5 Â 10 À 6 1C À 1 for 0% TiO 2 and 9.5 Â 10 À 6 1C À 1 to 100% TiO 2 . The values of thermal conductivity were low and increased with the increase of the volumetric fraction of TiO 2 , reaching a maximum (3.30 W/mK) for samples (40% TiO 2) sintered at 1000 1C/30 min. The measurements of electrical conductivity indicate that the obtained materials are electrical insulators ($10 À 10 S cm À 1).
