Abstract
The thermal decompositions of anhydrous fluorosilicates M(2)SiF(6) (M= Li, Na, R, Rb, Cs) and MSiF(6) (M=Ca, Sr, Ba) were investigated. The d ecompositions proceeded according to a simple acid-base mechanism with evolution of SiF4. The influence of the cationic counter-ion acidity (expressed by means of the electronegativity force) on the course of t hermal decomposition was estimated quantitatively.
