<jats:p>Simultaneous TG/DSC measurements performed on mixtures 2Li<jats:sub>2</jats:sub>CO<jats:sub>3</jats:sub>-5TiO<jats:sub>2</jats:sub> (anatase) subjected to high-energy milling showed that both the temperature and the enthalpy of Li<jats:sub>2</jats:sub>CO<jats:sub>3</jats:sub> decomposition are much lower than in the case of TG/DSC runs performed on a sample of a physical mixture. On the basis of the thermoanalytical evidence a solid-state synthesis of the spinel compound Li<jats:sub>4</jats:sub>Ti<jats:sub>5</jats:sub>O<jats:sub>12</jats:sub> has been proposed that combines mechanical (by high-energy milling) and thermal activation (8 h annealing at 973 K): the obtained compound shows a lattice constant in very good agreement with that expected for the pure phase Li<jats:sub>1+x</jats:sub>Ti<jats:sub>2−x</jats:sub>O<jats:sub>4</jats:sub> (x = 0.333). The molar heat capacity of Li<jats:sub>4</jats:sub>Ti<jats:sub>5</jats:sub>O<jats:sub>12</jats:sub> has been determined in the temperature range 323 - 633 K by quasi-isothermal Modulated Differential Scanning Calorimetry (MDSC). The specific surface area of Li<jats:sub>4</jats:sub>Ti<jats:sub>5</jats:sub>O<jats:sub>12</jats:sub> has been determined by gas adsorption</jats:p>
