potassium carbonate crystals,
potassium carbonate granular
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
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
2KOH + CO2 → K2CO3 + H2O

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.
• 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
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.
