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
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
appearance is colorless crystal or white granules and is easily
soluble in water with
its solution being strongly alkaline. Cool its saturated solution
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
generated through the reaction between potassium hydroxide with
Today, potassium carbonate is prepared commercially by the
potassium chloride. The resulting potassium hydroxide is then
carbon dioxide to form potassium carbonate, which is often used to

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,
photography, polyester, electroplating, leather, ceramic, building
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
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
• 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.
