Abstract

The objective of the study was to study the phases in the crystalline sentence of calcium molybdate with sodium metafanadat on the basis of phase equilibrium in binary sentence. For this sutyd, different mixtures are prepared based on different molar ratios and investigation is made about these different mixture physical properties. Finally, the study also draw a phase balanced chart for the studied substances. For methodology adopted, nine samples were prepared. The results shows that to form a solid solution as dissolving sodium metafandate in calcium molybdate up to 40% of sodium metafanadate and form a solid solution in this sentence confirms that the necessary conditions to form a soid solution. It is concluded that for difference less than 15%, unlimited solid solution is formed; whereas, for difference above 15%, limited solid solution is formed. Our conclusion also shows that these two elements solubility is limited where one possesses the characteristic of high electronegativity, while, the other possess the characteristic of low electro negativity.
