Anisotropic particles susceptibility

Can liquids in which the constituents are dipoles be ferroelectric For instance, if we could make a colloidal solution of small particles of the ferroelectric BaTi03, would this liquid be ferroelectric The answer is no, it would not. It is true that such a liquid would have a very high value of dielectric susceptibility and we might call it superparaelec-tric in analogy with the designation often used for a colloidal solution of ferromagnetic particles, which likewise does not show any collective behavior. An isotropic liquid cannot have polarization in any direction, because every possible rotation is a symmetry operation and this of course is independent of whether the liquid lacks a center of inversion, is chiral, or not. Hence we have at least to diminish the symmetry and go to anisotropic liquids, that is, to liquid crystals, in order to examine an eventual appearance of pyroelectricity or ferroelectricity.
