It is used as raw materials in manufacturing electro tube,TV kinescope,computer display.It is applied in optical glass improving clarity,strength and refractive index.It is also applied in electrode avoiding electric arc breaking-off during welding.It is used to produce food additives like potassium sorbate,monopotassium phosphate,etc.It is foliar spray
fertilizer and a constituent of compound fertilizer. In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing.It is absorbent removing hydrogen sulfide and carbon dioxide;Dry powder extinguisher mixed with soda; Auxiliary raw material for producing alcohol and acetone; And anti-aging agent in rubber production. Its solution is used in boiling and scouring of cotton cloth and wool's degreasing. In addition, it is also used in manufacture of printing ink, photograph-drug, polyester, explosives, electroplating, tanning, ceramic, building materials, crystals and medicine.

Chemical Properties | white powder or granules |
General Description | A aqueous solution of potassium hydroxide.Corrosive to metals and tissue.Density12.8 lb/gal. Used to make soaps, other potassium compounds, in liquid fertilizers. |
Air & Water Reactions | Water soluble. Addition of water evolves heat. |
Reactivity Profile | Potassium carbonate neutralizes acids exothermically to form salts plus water.Reacts with certain metals (such as aluminum and zinc) to form oxides or hydroxides of the metal and generate gaseous hydrogen.May initiate polymerization reactions in polymerizable organic compounds,especially epoxides.May generate flammable and toxic gases with ammonium salts,nitrides,halogenated organics,various metals,peroxides,and hydroperoxides.May serve as a catalyst.Reacts when heated above about 84°C with aqueous solutions of reducing sugars other than sucrose,to evolve toxic levels of carbon monoxide [Bretherick, 5th Ed.] |
Health Hazard | TOXIC;inhalation,ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes.Avoid any skin contact.Effects of contact or inhalation may be delayed.Fire may produce irritating,corrosi ve and/or toxic gases.Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
Fire Hazard | Non-combustible,substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.Some are oxidizers and may ignite combustibles (wood,paper,oil,clothing,etc.).Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. |
