Molecular weight:  611.77
CAS NO.:                 10124-56-8
HS Code:                283531900
EINECS:               233-343-1

Appearance:         White granular crystal or powder
Density:                2.484g/cm3
Melting point:        616ºC
Boiling Point:        1500ºC
Solubility:              Soluble in water, insoluble in organic solvents
Attributes:             Strong hygroscopicity, sticky after moisture absorption, easy deliquescence in air and easy dissolution in water; The solubility in water is high, but the dissolution rate is warm; The aqueous solution is acidic. Easily hydrolyzed into phosphite. It has the ability to form soluble complexes for some metal ions (calcium and magnesium), so it can be used to soften water and form complexes with lead, silver and barium salts.
 
It is used in refractory materials, water treatment, washing, leather, medicine, printing and dyeing, textile, mineral processing, rinsing, paper making, etc.
