MANGANESE
(Mn)
MATERIAL
OVERVIEW
Characteristics:
There are four allotropic forms, of which alpha is
most important. Brittle, silvery metal. Decomposes in
water, readily dissolves in dilute mineral acids. Pure
Manganese cannot be fabricated. Manganese is
considered essential for plant and animal life.
Hazards:
Tolerance, (fumes) 1 mg/m3
of
air, (metal and most compounds) 5 mg/m3 of air. Dust or powder is flammable. Use dry
chemical to extinguish.
