Versuchsvorschrift

A TBL slurry was prepared according to the method disclosed in Japanese Patent Publication No. 1149/67. More specifically, 8.162 Kg of powdery lead monoxide (PbO-DP) was charged in a high-speed stirrer-equipped, 60-liter capacity vessel filled with 10 l of water, and high speed agitation was conducted for 10 minutes to disperse the powder sufficiently homogeneously and the dispersion was heated at 65° C. Then, 50.8 cc of an acetic acid solution having a concentration of 2.7 moles/liter was added as a catalyst, and 1306 cc of sulfuric acid having a concentration of 7 moles/liter was dropped to the lead monoxide slurry over a period of 40 minutes and aging was conducted under agitation at 65° C. for 60 minutes to form a slurry of needle crystals of tribasic lead sulfate (Sample No. TBL-Hl).
