| Popis: | The specific pore volume, v, and solids' density, d, were determined for the pastes of unformed lead--acid battery plates by a simple laboratory technique. v was found to vary linearly with the apparent density of the dry paste, D, according to v = 0.356 - 0.0569D for pastes cured to develop 4PbO x PbSO/sub 4/ and v = 0.271 - 0.0415D for pastes otherwise cured, d was determined from the relationship d/sup -1/ = D/sup -1/ - v. d decreased continually with decreasing D for all plates except those cured to develop 4PbO x PbSO/sub 4/. For the latter plates d went through a maximum as D decreased. This maximum is explained in terms of the differing crystalline perfections of the 4PbO x PbSO/sub 4/ crystals in the plates. |
