Hexagonal Close Packed (HCP) phase Copper-zinc (Cu1-x Znx) alloys have been discussed with compositions (x = 79.20, 82.00, 84.30, 86.10, 97.10, 97.50, 98.10, 98.60, 99.50). These alloys have been prepared from spectroscopically pure copper (Cu) and zinc (Zn) metals by melting using the glass blowing and vacuum sealing process with appropriate quantities in evacuated quartz tubes. For the duration of melting process the alloy/mixture was systematically stirred to get homogenization alloy. The powder samples of all the Cu1-x Znx alloys were prepared by gently filing the ingots with jeweller’s file. The evaluated Debye temperature values were compared with Debye temperature values evaluated from Kopp-Neumann relation and other four relations composition dependence relation, specific heat relation, empirical relation, Gril and Mittra relation. Gruneisen constant of hcp phase Cu1-x-Znx alloys were evaluated utilizing a relation associated with Debye temperature values were measured from X-Ray diffraction method.

Ion-conductance, prfencial solvation by Walden product pressure coefficient pressure coefficient and Hydrodynamic Radii correlated with different electrolytes with in solvents is formed by diverse aspects like cohesive energy density, relative viscosity, solvent dielectric constant values of intermediate, with in duel mixture associations of its solvent adesive solvent measures. Sodium saltion solvent interactions of solute ion with solvent core. Conductance data and physical properties of ion viscosity electrolytes are used by change of the sodium salt ion conductance values, Walden product pressure coefficient and Hydrodynamic radii behavior of the ions and these are measured for derived Sodium salt of Methane Sulphonic acid electrolytein water-MeOH and water-DMF of dissimilar composition in the heat choice of 283K to 313K. A o values KA of electrolyle sodium saltion pair, Association constant values figured out with Shedlovsky Extrapolation method. A°rise with composition of pure water solvent in organic aqueous duel mixture composition in binary sheeth. KA value is more in 80% water-MeOH composition signifying sodium saltion of sodium solvention interactions are more at this binary composition of solvention and thermodynamic properties for the function of specified sodium saltion solvent interaction in composition for structural effects.
