Applications

Potassium Phosphate Dibasic has wide applications in the new energy, electronics, pharmaceutical, food, agricultural, and industrial sectors.

• New Energy Industry: In the field of lithium batteries, it is used as an electrolyte additive to improve the stability of the SEI film and enhance the cycle life of batteries; it also serves as a raw material in the production of new energy batteries to assist in optimizing battery performance.
• Electronics Industry: It is used for semiconductor cleaning, where it is formulated into a solution to remove metal ions and organic contaminants from the surface of silicon wafers, ensuring the cleanliness of silicon wafers; it can also be used as a cleaning agent and surface treatment agent for electronic components to support the stable operation of the components.
• Pharmaceutical Industry: In pharmaceutical preparations, it acts as a pH regulator and buffer to adjust the pH of oral liquids, injections, and other preparations, ensuring the stability of drugs. Pharmaceutical-grade products have strict requirements for purity and impurity control; in cell culture, it serves as a component of culture media, providing phosphorus and potassium elements and maintaining pH stability to increase the yield of fermentation products; it is also used in vaccine formulations and diluents to ensure vaccine stability, and in clinical settings, it can be used as an electrolyte supplement to maintain the electrolyte balance in patients’ bodies.
• Food Industry: In the beverage industry, it functions as an acidity regulator and pH buffer to adjust the pH of carbonated drinks, coffee, and other beverages, preventing protein denaturation, preserving flavor, and extending the room-temperature shelf life; in the dairy industry, it is used as an emulsifier and stabilizer to prevent milk from coagulating when heated and improve texture and taste; in meat products and baked goods, it plays roles in water retention and improvement, and leavening respectively, enhancing product quality and shelf life; in the fermentation industry, it acts as a buffer and nutrient to ensure the stability of the fermentation process and improve the purity of fermentation products.
• Agricultural Industry: In crop cultivation, it is used for food crops and fruits/vegetables. It can be applied alone or in combination with regulators to promote growth, increase yield and quality, and enhance stress resistance; in livestock breeding, it is used as a feed additive to supplement phosphorus and potassium elements, alleviate heat stress in poultry, and increase milk production in dairy cows; in aquaculture, it is used for water quality regulation and nutrient supplementation to improve water quality, stabilize pH, decompose harmful substances, and promote the reproduction of algae and the growth of aquatic animals.
• Industrial Sector: In the water treatment industry, it serves as a water quality stabilizer and water softener to soften water, inhibit pipe scaling, and treat heavy metal ions in industrial wastewater; in the electroplating industry, it is used as an additive and buffer to improve the quality and uniformity of coatings and maintain the stability of electroplating solutions; in textile dyeing and printing, it adjusts the pH of dye baths and enhances dyeing effects and color fastness; in the paper industry, it adjusts the pH of pulp and improves the strength and gloss of paper; in the ceramic industry, it acts as a flux in glazes to lower the melting temperature and improve fluidity and gloss; it is also a raw material for phosphorus-based flame retardants, used in fire protection treatments for wood, paper, and other materials.

In addition, Potassium Phosphate Dibasic also has small-scale applications in niche fields such as laboratory chemical analysis (e.g., preparation of buffer solutions) and some daily chemical additives (e.g., auxiliary components in high-end cleaning agents).

Storage & Handling
