英文名:
Sodium Hexametaphosphate(Sodium Polyphosphates, Glassy; Sodium Tetrapolyphosphate; Graham’s Salt)
Chemical formula: (NaPO3)6
CAS No.:10124-56-8
Molecular weight: 611.82
Standard executed: HG/T2837-1997
Properties: White powder, relative density is 2.484 (20), easily soluble in water, but not in organic solution, absorbent to dampness, and turn sticky when absorbed dampness in air. It is possible to form solvent compound with metallic ions such as Ca, Ba, Mg, Cu and Fe; It is a fine agent for water treatment.
