Abstract

Powders and films of amorphous, cubic and monoclinic antimonic acids are prepared. Their water sorptioh isotherms and the water desorption spectra are measured. The protonie conductivities are very sensitive to water vapor pressure and are discussed with the amount of water. The amorphous and cubic antimonic acids contain larger amounts of water than the monoclinic acid, which can be attributed to the existence of micropores in the structures.
