99% K2CO3 UN NO 1760 white dipotassium carbonate powder can be used for the production of optical glass


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.

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.
