It is modified matrix of anatase in turn of the thermal and laser treatments. Thedependence of Gibbs energy change of the intercalation reaction of lithium with the guest loaddegree change was analyzed. Laser irradiation turned out to increase twice the value of maximumlithium “guest” loading, constricting heterophase area and changing contrarily concentrationgenesis of temperature dependence of entropy of lithium dilution. The optimal conditions of laserirradiation nanodispersive anatase (pulse energy E = 0,02 J, pulse duration τ = 15 ns repetitionfrequency f = 28 Hz, duration of exposure to 5 min.), at which specific energy characteristics of LPS,formed on its basis, increased by 55% is set

Wilson And Nrtl Equations

Temperature dependence of GE is discussed for three widely used equations linear and nonlinear in parameters. It is shown that the Wilson equation predicts always positive excess heat capacity regardless of values of its parameters. Several temperature modifications of the Redlich-Kister, Wilson and NRTL equations are discussed with respect to the sign of the excess Gibbs energy, excess enthalpy and excess heat capacity.

Increasing Temperature

In the heat «cooling» investigated the temperature dependence of the specific heat capacity and thermodynamic functions doped strontium alloy AK1М2 in the range 298,15—900 K. Mathematical models are obtained that describe the change in these properties of alloys in the temperature range 298.15—900 K, as well as on the concentration of the doping component. It was found that with increasing temperature, specific heat capacity, enthalpy and entropy alloys increase, and the concentration up to 0.5 wt.% of the alloying element decreases. Gibbs energy values have an inverse relationship, i.e., temperature — decreases the content of alloying component — is up to 0.5 wt.% growing.
