Vibrational Relaxation in the Solid NaNO3–NaClO4, NaNO3–NaNO2, and Na2CO3–Na2SO4 Binary Systems

Comprehensive study of the synthetic tychite, Na6Mg2(CO3)4SO4: synthesis, structure and conductive properties

“…The endothermic peak at 824 °C may be associated with the melting of the Na 2 CO 3 –Na 2 SO 4 solid solution. 42…”
