Product Description
Food Grade Potassium Dihydrogen Phosphate K2HPO4 Additive
Potassium Dihydrogen Phosphate is a high-efficiency phosphorus-potassium compound fertilizer and a versatile functional additive, known for its high nutrient content, excellent water solubility, and superior buffering capacity. It serves as a crucial input in precision agriculture, the food industry, and various industrial processes. The product is typically manufactured through the neutralization of food-grade or technical-grade phosphoric acid with potassium hydroxide, followed by crystallization, purification, and drying.
