Manganese Pieces

MATERIAL OVERVIEW

Characteristics: Manganese is a silvery-gray metal which resembles iron. Hard and very brittle, it is difficult to fuse, easy to oxidize, decomposes in water and readily dissolves in dilute mineral acids. Like iron, it tarnishes in air and rusts. Pure manganese cannot be fabricated and is found as a free element in nature (often combined with iron) and in many other minerals. There are four allotropic forms, of which alpha is most important.

Manganese phosphating is used in iron and steel production as a treatment for rust and corrosion prevention on steel as well as an alloying agent for aluminum to increase resistance to corrosion. Methylcyclopentadienyl manganese tricarbonyl is used as an additive in unleaded gasoline to boost octane rating and reduce engine knocking.

Hazards: Manganese compounds are less toxic than those of most metals. Exposure to manganese dust should not exceed 5 mg/m3 even for short periods because of its toxicity level. Tolerance for fumes should be at 1 mg/m3 of air or below. Although Manganese is a required trace mineral essential for all known plant and animal life, in larger amounts, particularly through inhalation, it has been linked to neurological damage, impaired motor skills and cognitive disorders, that are often irreversible. Use dry chemical to extinguish.
