LnGa0.5Sb1.5O6 Complex Oxides with a Rosiaite-Type Structure: Synthesis, Structure, and Thermal Properties

Thermal properties of matter within the model of a two-phase system

“…here the entropies are: of the original phase Thus, locallyequilibrium entropy (15) coincides with its substantive determination (14) subject to satisfaction of equality ε T = 0, which generates formula (8).…”

“…is related to temperature T x (q), at which the maximum of the first derivative from the volume fraction of phase 1 u x (q) = (dx 1 /dT ) T =Tx and the extremum of phase transition heat are observed. 8) is as follows with account of ( 9)…”

“…Table 1 gives the model parameters for complex oxides discussed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. As an example, Fig.…”

“…An adequate description of experimental data on heat capacity of various substances by the logistic function (8) allows for using it to describe other thermal properties as well, e.g., thermal expansion coefficients.…”

“…Experimenters are currently showing a constant interest in studying the heat capacities of complex oxides [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. It is due not only to their technical use (e.g., ceramics [15]), but also the uniqueness and diversity of physical properties.…”
