Curing and drying of plates for lead acid batteries can be managed to become tetra basic or tri basic lead sulfate depending on the process parameters. In the following a short overview of the possibilities are outlined. We will consult to adopt the best curing process on request. Remark: In case of reactive ball mill oxide a fast and complete nucleation is achieved by applying steam for about 1 h. In traditional batch curing chambers a dry out of the paste during the curing (nucleation phase) often takes place. The result will be small tri basic crystals coming along with loss on porosity. To avoid any tetra basic lead sulfate Lignin compounds as inhibitors will be used.
