Physical properties of Electrolytic Manganese Dioxide (Part 1)

Study of Properties of Grinding and Wear

Abstract

Electrolytic Manganese Dioxide (EMD) is in general used for dry-batteries. This paper describes the physical properties of EMD, such as grinding, wear and crystal structures of BET surface area. The results obtained as follows;
1)Grinding index increases continuously with increase of BET surface area. Range of work index(Wi) is 14-22 [KWH/T] .
2)Lattice parameter b increases with increase of BET, accompanied with decrease of crystalline size and increase of distorsion.
3)Wear index decreases with increase of BET surface area and also with decrease of particle size.
