The values of specific pore volume, v, and the density of solids, d, were determined for unformed lead--acid battery pastes prepared from 4PbO . PbSO/sub 4/; v varied with D, the apparent density of the dry paste, according to v = 0.398 -0.0698D. The parameters d and D were related by d = D (0.0698D/sup 2/ - 0.398D + 1)/sup -1/. By that relationship, however, d is variant with D, an unexpected result. It is proposed that the variance results because the crystals of 4PbO . PbSO/sub 4/ tend to orient in tight bundles, especially for the pastes with the highest values of D. Such bundles entrap open pits on the crystal surfaces, and the measured values of d are then reduced.
