Abstract
A solid state reaction method for the production of tetrabasic lead sulfate includes the steps of mixing a stoichiometric mixture of 5PbO and (NH4)2SO4 and heating the stoichiometric mixture of 5PbO and (NH4)2SO4 at a temperature between 500 and 700° C. for 3 to 8 hours. The method also includes the steps of deagglomerating and sieving resulting tetrabasic lead sulfate.
