N2 - An empirical model is presented as a possible mechanism for the acoustic wave attenuation in porous polycrystalline ceramics containing small amounts of volatiles. The mechanism involves changes in the distribution of adsorbed volatiles at crack and grain boundaries. The model is supported by data on PZT, glass, and very extensive data on olivine basalt including measurements as a function of volatile vapor pressure, temperature, and volatile type. The theoretical approach is based on a thermally activated diffusion process for the adsorbed volatile molecules.
