►Description 

 

       Potassium carbonate is the primary component of potash and the more refined

 

pearl ash or salts of tartar. Historically, pearl ash was created by baking potash in a

 

kiln to remove impurities. The fine, white powder remaining was the pearl ash. The

 

first patent issued by the US Patent Office was awarded to Samuel Hopkins in 1790

 

for an improved method of making potash and pearl ash.

 

In late 18th century North America, before the development of baking powder, pearl

 

ash was used as a leavening agent in quick breads.

 

 

     Potassium carbonate (chemical formula: K2CO3), 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.

 

      Today, potassium carbonate is prepared commercially by the electrolysis of

 

potassium chloride. The resulting potassium hydroxide is then carbonated using

 

carbon dioxide to form potassium carbonate, which is often used to produce other

 

Potassium compounds.

►Application

 

     

       

   Potassium carbonate light  can be used for the production of optical glass and

 

can increase the transparency, strength and refractive co-efficie.

 

     In addition, it can also be applied to the production of inks, pharmaceutical for

 

photography, polyester, electroplating, leather, ceramic, building materials, crystal,

 

potassium soap and medicine. Heavy potassium carbonate is mainly used as the

 

raw material of production of kinescope glass shell and is widely used as the raw

 

material of glass and special glass materials as well as being used for the

 

decarbonization of chemical fertilizer.

► Preventative Measures

 

 

•  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. 

 

 

 

►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.
