molecular formula: Na4P2O7·10H2O
molecular weight: 446.05
Character: Achromaticity single oblique crystal serial or white powder, comparative density 1.824.Resolvable in water, but not in ethanol, its aqueous solution appears alkalescence, when heated to 100 degree, lose all the crystalloid, water when the aqueous solution heated to ebullition, and it will be hydrolyzed into Positive Sodium Hydrogen Phoisphate. Uncovered in air, it is easy efflorescent.
Purpose: Accessory ingredient for dyeing, stabilizer, stabilizer for toothpaste friction producing material, regulator for dust in oil well, fusion agent for electroplating solution.
