Abstract

Colloidal lead oxide is obtained by treating lead oxide and water in a Plauson mill, steam being passed through the jacket of the mill to bring the temperature to 80-100 DEG C.ALSO:Lead arsenate is obtained by reacting with arsenic acid upon a colloidal solution of lead oxide in water, aqueous solution, or other suitable dispersion medium, preferably at a raised temperature. The arsenate precipitates in a finely divided form. An example describes the production of the arsenate PbHAsO4 in this manner, the colloidalizing of the lead oxide in water being effected in a Plauson mill, steam being passed through the jacket of the mill so as to raise the temperature to 80-100 DEG C. The arsenic acid is run into the mill, and the reaction is effected in a few minutes.
