Potassium dihydrogen phosphate
Potassium dihydrogen phosphate (KDP) is a colorless, hygroscopic, odorless, granular, or crystalline powder. It is freely soluble in water and practically insoluble in alcohol. KDP is an essential phosphate salt with outstanding ferroelectric, piezoelectric, electro-optic, and non-linear optical properties. It is commonly used in high-energy laser systems, light frequency converters, and Pockels photoelectric switches in laser systems. Besides high-tech applications, potassium dihydrogen phosphate is a popular phosphate fertilizer ingredient. Other applications include:
· high temperature electrolyte
· dopant
· Phosphonates precursor
· raw material for single crystal growth
· phosphate buffer ingredient
· high-quality ceramic precursor
