A model is proposed for the formation of the ferroelectric solid-liquid interface in a non-electrolyte dispersion system. Bulk properties as well as the surface properties of the dispersed solid could be a factor which was associated with various characters of the dispersion state. A qualitative investigation was carried out to see whether the continuum polarization process in solid-liquid interface due to the inhomogeneous field from the polar solid might affect the powder dispersion. The development of the polarized solid-liquid interface might depend on the polarity of solid particle and of liquid medium, shapes, mobility, and solubility of the molecules in the liquid phase, and temperature. Two possible effects of polarized solid-liquid interface on the dispersion stability are discussed. Lastly, this model was applied to interpreting some experimental results of adhesion. 17 refs.
