Potassium Carbonate Sesquihydrate

Potassium Carbonate Sesquihydrate

Potassium carbonate sesquihydrate is a salt consisting of potassium (K⁺) cations, carbonate (CO₃²⁻) anions, and water molecules (H₂O) bound in a 2:1.5 ratio with the carbonate.

Chemical Formula: K₂CO₃ • 1.5H₂O

CAS Number: 6381-79-9

Grade: ACS, USP, FCC

Appearance:  A white, crystalline solid

Uses:

• Precursor: A starting material for the production of various other potassium compounds.

• Drying Agent: While not its primary use, it can release water upon heating (dehydration), potentially acting as a drying agent.

• Food Additive: It is used as a food additive or as a dough conditioner or pH regulator in some countries.

Industry and Common Applications:

• Glass Manufacturing: It is used as a fluxing agent in the production of glass and ceramics.

• Food Industry: It helps adjust acidity levels, enhance food texture, and improve fermentation processes.

• Textile Industry: It is used in agriculture as a source of potassium in fertilizers and soil amendments.
