ABSTRACT:
Highly oxidized lead powder containing red lead not more than 90% is efficiently produced by maturing the lead powder material at a low temperature section of a furnace keeping the temperature less than 100.degree. C. by spraying water to the material and then, by heating the same from 400.degree. to 500.degree. C. at a high temperature section of the furnace. The highly oxidized lead powder produced in this method is preferable as active material of a lead storage battery, that is, a paste preparation and formation treatment become easy and a long life electrode is obtained.
