Rat oral LDso:>40mmol/kg. Manganese oxide dust can cause manganese pneumoconiosis in humans. Staff should be protected. The working environment should be well ventilated. Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source. Packaging is required to be sealed and not to be in contact with air. Moisture-proof, sunscreen. Should be stored separately from reducing agents, flammable materials, combustible materials, oxidizing agents, etc.1313-13-9 - Toxicity:
See chemical manganese dioxide. Manganese oxide dust can cause human manganese pneumoconiosis. High-valent manganese oxides, regardless of the way they invade the body, have toxic effects on the brain. See metal manganese for others.1313-13-9 - Use:
Manganese Dioxide (MnO2) is a strong oxidant, mainly used as depolarizing agent for dry batteries, decolorizing agent for glass industry, desiccant for paint ink, gas mask absorbent, match combustion aid, etc. mainly used as depolarizing agent for dry batteries. It is a good decolorant in the glass industry, which can oxidize low-priced iron salts to high-iron salts, turning the blue-green of glass into weak yellow. Used in the electronics industry to make manganese-zinc ferrite magnetic materials. Used as a raw material for iron-manganese alloys in the steelmaking industry and a heating agent for the casting industry. Used as an absorbent for carbon monoxide in gas masks. Used in the chemical industry as an oxidant (such as purple red synthesis), a catalyst for organic synthesis, a desiccant for paints and inks. It is also used as an accelerant for the match industry, as a raw material for ceramics, enamel glaze and manganese salt. It is also used for pyrotechnics, water purification, iron removal, medicine, fertilizer and fabric printing and dyeing. It is used in the chemical industry to produce manganese sulfate, potassium permanganate, manganese carbonate, manganese chloride, manganese nitrate, manganese monoxide, etc. Manganese sulfate is used as a fertilizer and feed additive. The pharmaceutical sector uses manganese compounds as disinfectants, oxidants, catalysts, gastric lavage agents and emetic agents. Manganese is used as a desulfurizer for dry batteries and nitrogen fertilizer production; it is also widely used in metallurgy, ceramics, glass, light industry, machinery, matches, electronics, dyes, national defense, communications, environmental protection and other departments. See Chemical Manganese Dioxide. It is used as a depolarizer for dry batteries, a catalyst and an oxidant for the synthesis industry, a colorant, a disinfectant, and an iron remover for the glass industry and the enamel industry. Used in the manufacture of metallic manganese, special alloys, ferromanganese castings, gas masks and electronic materials such as ferrite. In addition, it can also be used in the rubber industry to increase the viscosity of rubber. Oxidant, special alloy steel, catalyst, desiccant, determination of sodium sulfide in cement. It is widely used in steelmaking and in making glass, ceramics, enamel, dry batteries, etc. Used as an oxidant, also used in steelmaking, glass, ceramics, enamel, dry batteries, matches, medicine, etc.
