Product Description

White powder potassium carbonate mainly used for making glass CAS NO 584-08-7




       Potassium carbonate , also known as potash; its appearance is colorless


crystal or white granules and is easily soluble in water with its solution being


strongly alkaline. Cool its saturated solution with generating glassy monoclinic


crystalline hydrate 2K2CO3 • 3H2O separated. It has a density of 2.043. It will lose


its crystal water at 100 ℃. It is insoluble in ethanol, acetone and ether. It has a


strong hygroscopic effect and can absorb carbon dioxide and water upon exposure


to air to be converted into potassium bicarbonate. It can be generated through the


reaction between potassium hydroxide with carbon dioxide to give. You can also


obtain it through the heating reaction between potassium chloride and magnesium


carbonate, water and carbon dioxide under pressure or obtain it through the


impregnation of tung seed ash and plant ash. It is mainly used as the raw material


for synthesis of decarbonization gas, electronic tubes, glass, enamel, printing,


welding, film developing, inorganic salts and kinescope glass shell. The impure


potassium carbonate base is usually called base, Tong base or pearl grey and is


one kind of early species of potash.

Hand protection: handle with gloves.


Eye protection: safety glasses.


Skin and body protection: choose body protection according to the amount and


concentration of the dangerous substance at the work place.


Handle in accordance with good industrial hygiene and safety practice. Wash


hands before breaks and at the end of workday.


Accidental release measures. Use personal protective equipment. Avoid dust


formation. Avoid breathing dust.


If breathed in, move person into fresh air. If not breathing give artificial respiration


Consult a physician. In case of skin contact, wash off with soap and plenty of water.


Consult a physician. In case of eye contact, rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.


If swallowed, never give anything by mouth to an unconscious person.


Rinse mouth with water. Consult a physician.




►Safe Storage 




Dry. Separated from strong acids.


Storage Conditions Keep tightly closed.


Potassium carbonate is stored in bunkers; the ventilation air must be dry because


of the hydroscopicity of the product.


Keep container tightly closed in a dry and well-ventilated place.
