Thermogravimetric and corrosion studies, And Phase Equilibria for Lithium, Sodium and Potassium Carbonates

摘要

Results of thermogravimetric studies on lithium and potassium carbonate in vacuum and in an atmosphere of CO2 up to 600° C are reported. Corrosion studies including tests on platinum, silver, gold, boron nitride and single crystals of magnesium oxide are described. A report on studies in progress of the phase equilibria for the ternary system Li2C03-Na2CO3-K2CO3 is given together with the equilibrium diagrams for the three possible sets of binary mixtures for these carbonates.
