실험 절차
A 2-liter beaker was charged with 1175.6 ml of the lead monoxide slurry A-3 (containing 0.587 g of PbOn) and the slurry was heated under agitation with a glass vane, and when the temperature was elevated to about 70° C., 26.22 ml of sulfuric acid having a concentration of 3.86 mole/l was promptly added to the slurry in about 10 seconds (the pH value was 6.2 at the initial stage of addition). The temperature was maintained at 65° to 70° C. while heating the slurry on a heater under agitation, and in this state, aging was carried out for 60 minutes to obtain a base slurry of tribasic lead sulfate.
