| Popis: | Differential-thermal and thermogravimetric analyses are used to study the oxidation of titanium disilicide in a nonisothermal regime in the temperature range 300–1250 K with a heating rate in air of 10 deg/min. Experimental results are compared with theoretical Criado curves. An oxidation mechanism is established. The activation energy for oxidation is calculated: E = 127.03 kJ/mole, and thermodynamic parameters are calculated for activation, i.e., entropy, Gibbs free energy, enthalpy: ΔS# = −165.54 J/(mole · K), ΔG# = 277.53 kJ/mole, ΔH# = 119.47 kJ/mole, respectively. |
