چکیده
The enthalpies of mixing of the liquid mixtures of (NaB0 2 ) 2 + B 2 0 3 , N a 4 P 2 0 7 + (NaP0 3 ) 2 , (NaP0 3 ) 2 + B 2 0 3 and N a 4 P 2 0 7 + (NaB0 2 ) 2 have been measured by liquid -(liquid calorimetry. The results are discussed in terms of tentative structural models of the melts, and in terms of O 2 ion transfers from phosphorus groups to boron groups in (NaP0 3 ) 2 + B 2 0 3 and from boron groups to phosphorus groups in Na 4 P 2 0 7 + (NaB0 2 ) 2 .

Thermodynamic analysis of nanocrystalline solid solution formation in the W-Co-Si ternary system by mechanical alloying
Co3W2Si intermetallic compound was synthesized by mechanical alloying (MA) of W, Co and Si elemental powder mixtures. The phase composition of the milled products was evaluated by X-ray diffraction (XRD) analysis. Morphological evolutions were characterized by transmission electron microscopy (TEM). The results showed that high energy ball milling performed in the present work led to the format...
متن کاملThe Prediction of Surface Tension of Ternary Mixtures at Different Temperatures Using Artificial Neural Networks
In this work, artificial neural network (ANN) has been employed to propose a practical model for predicting the surface tension of multi-component mixtures. In order to develop a reliable model based on the ANN, a comprehensive experimental data set including 15 ternary liquid mixtures at different temperatures was employed. These systems consist of 777 data points generally containing hydrocar...

The purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. Experimental solubility curves and tie-line points for the system were obtained at T = 298.2, 308.2 and 318.2 K and ambient pressure. The binodal curve data were detected by the cloud point method. The mass fractions of each layer ...
متن کاملThermodynamics of ternary electrolytes: Enhanced adsorption of macroions as minority component to liquid interfaces.
We study the equilibrium thermodynamics between two ternary ionic systems in immiscible solvents characterized by different dielectric constants. We consider system geometries wherein the two phases of immiscible solvents occupy, respectively, semi-infinite regions of space separated by neutral and charged planar interfaces. Specifically we analyze the case where the ternary system is composed ...

In this work, the mean activity coefficients of KCl in the KCl+lactose +water system were determined using the potentiometric method. The electromotive force measurements were carried out on the galvanic cell without liquid junction of the type: Ag|AgCl|KCl (m), lactose (wt.%), H2O (1−wt.) %|K-ISE, in various mixed solvent systems containing 0, 5,7.5, 10 and 12.5 % mass fractions of lactose.
