| 20100143219 | PROCESS FOR THE PRODUCTION OF NANO LEAD OXIDES - Provided is a process for producing fine particles of pure lead oxide from a waste lead oxide paste obtained from exhausted lead-acid batteries. The lead oxide particles so produced are substantially spherical and have a weight average particle size from about 13 nm to about 100 nm, which, are of nano-particle dimensions. The process according to the present invention is capable to produce pure lead oxide of PbO2 and lead oxide of Pb3O4 or commonly known as red lead. | 06-10-2010 |
