Alkali disilicates (lithium, sodium, potassium, rubidium, caesium) have been synthesized and the temperature, enthalpy and entropies of melting measured by differential calorimetric analysis. Unknown solid-solid transitions were detected for sodium and caesium disilicates. New X-ray diffraction patterns are given to characterize each disilicate.
