Sodium Hexametaphosphate
Molecular Formula: (NaPO3)6
Molecular Weight: 611.77
CAS No.: 10124-56-8
HS Code: 28353919
Aliases: Sodium metaphosphate, Graham’s salt, hexametaphosphate, SHMP
Characteristics: With a melting point of 616°C, the compound is highly soluble in water but insoluble in organic solvents. Its aqueous solution exhibits an acidic reaction and demonstrates strong hygroscopic properties, gradually absorbing moisture from the air to form a viscous gel. It effectively forms soluble chelates with metal ions such as Ca, Ba, Mg, Cu, Fe, making it an exceptional water treatment agent.
