ANALYSIS OF FUSION AND CRYSTALLIZATION PROCESSES OF CRYSTALLINE HYDRATES ON BASIS OF FUSIBILITY THERMOGRAMS

On basis of heating and cooling thermograms analysis of fusion, dehydration, hydration and solidification processes of crystalline hydrates Na2S2O3*5H2O, Na2SO4*10H2O, Na2SO3*7H2O, Na2CO3*10H2O and Na2CH3COO*3H2O is given. Hydrates structurization schemes in the liquid state are offered. The interpr...
