Application-Specific Uses

 

 

Acidity Regulation: Functions as an effective acidity regulator and buffering agent in food and beverage formulations, carrying the E number E332.
Pharmaceutical Formulation: Utilized in the pharmaceutical sector as an active ingredient in medications targeting hypokalemia and for urine alkalinization.
Nutritional & Agricultural Inputs: Serves as a key elemental component in high-efficiency compound fertilizers and specialized plant nutrition products.
Industrial & Specialty Processing: Employed in secondary manufacturing applications, specifically within paper-making processes and surface gilding operations. 

 

Physical Form & Handling

 

 

Appearance & Organoleptic Profile: White crystalline powder or crystals; odorless with a saline taste, suitable for food formulation.

Hygroscopic Behavior: Slightly hygroscopic and readily deliquescent; keep sealed and minimize exposure to humid air to limit moisture uptake and clumping.

Relative Density: Relative density is approximately 1.98, relevant to bulk handling and packaging volume calculations.

Thermal Behavior: Melts and decomposes at approximately 230°C; avoid unnecessary exposure to temperatures near the decomposition point during processing.

 

Solubility & Processing Characteristics

 

 

Aqueous Solubility: Dissolves rapidly and completely in water, producing a clear, stable solution that integrates seamlessly into liquid formulations without leaving residue.

Dry Powder Blending: Suitable for dry blending and premix applications. Particle size and handling characteristics can be confirmed against the supplied specification where required.

Processing & Shear Tolerance: Withstands standard industrial mixing and mechanical shear forces, though equipment should be monitored to prevent localized heat buildup near thermal limits.

 

Packaging, Storage & Bulk Supply

 

 

Standard Packaging: The product is available in 25 kg net paper bags, suitable for conventional bulk ingredient handling and warehouse storage.

Bulk Packaging: For larger-volume orders, 1 MT big bags with PE liners are available to reduce the number of individual packages handled during bulk logistics.

Moisture Protection: PE liner helps protect the product from moisture during storage and transportation.

Storage Conditions: Store the product in a dry environment with the original packaging properly sealed to limit moisture exposure and maintain the supplied physical condition.
