What is Trimanganese tetraoxide?
Chemical properties
Grass-green powder. but converted to Mn 3O4 if heated in air. Soluble in acids; insoluble in water. Noncombustible.
The Uses of Trimanganese tetraoxide
Textile printing, analytical chemistry, catalyst in manufacture of allyl alcohol, ceramics, paints, colored glass, bleaching tallow, animal feeds, fertilizers, food additive and dietary supplement.
General Description
Manganese(II,III) oxide is a transition metal oxide that is formed by annealing manganese oxide in the air above 1000°C. It can be used for a variety of applications such as catalysis, electrochromic devices, and other energy storage applications.
Reactivity Profile
Trimanganese tetraoxide is non-combustible but decomposes, generating toxic fumes when strongly heated strongly in the air. A good oxidizing agent. Reacts with hydrochloric acid to form gaseous chlorine and soluble manganese salts.
Hazard
Chronic manganese poisoning and pulmonary effects.
Health Hazard
Manganese tetroxide affects the central nervous system, and toxicity occurs mostly in chronic form (manganism).
Flammability and Explosibility
Non flammable
Safety Profile
Experimental reproductive effects. Reacts violently @ <l00℃. See also MANGANESE COMPOUNDS.
