​Sodium Metaphosphate

Product Information

Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are all sodium polyphosphates made of repeating units of NaPO3. Sodium Metaphosphate generally refers to a long chain of NaPO3 units that is not soluble in water, which is why it is sometimes called insoluble metaphosphate. Sodium Trimetaphosphate has three NaPO3 units, and Sodium Hexametaphosphate has six NaPO3 units. Both the Trimetaphosphate and the Hexametaphosphate are soluble in water. In cosmetics and personal care products, Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are used in the formulation of makeup foundations, mascara, bath products, and moisturizing and skin care products.Sodium Metaphosphate, Insoluble, occurs as a white, crystalline powder. It is a high-molecular-weight sodium polyphosphate composed of two long metaphosphate chains (NaPO3) that spiral in opposite directions about a common axis. The Na2O/P2O5 ratio is about 1.0. It is practically insoluble in water but dissolves in mineral acids and in solutions of potassium and ammonium (but not sodium) chlorides. The pH of a 1:3 slurry in water is about 6.5.

Sodium Metaphosphate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. ATT produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available.

Applications of  Sodium Metaphosphate

Sodium Metaphosphate uses and applications include: Polishing agent, abrasive, thickener in toothpaste; oral care agent; detergent builders; abrasive detergents; polishing agents; water softening; sequestrant; emulsifier; textile processing; corrosionscale control in drinking water treatment; laundering; food additive (sequestrant, emulsifier, texturizer, binding agent, alkaline agent); preparation of food starch modified; buffer, chelating agent in cosmetics

Dihydrogen phosphate is suitable for low melting point low TG glass, phosphate optical glass, phosphosilicate optical glass, sealing glass powder of special optical glass, analytical reagents, adhesives, refractory materials, etc. Aluminum dihydrogen phosphate can be used as raw material for sealing glass powder with low melting point, and as raw material for high-aluminum glass-ceramics used in laser gyroscopes. Liquid aluminum dihydrogen phosphate is used in the field of metal surface treatment as anti-rust treatment phosphating solution. High-purity potassium dihydrogen phosphate is used to manufacture KDP and KTP crystal raw materials, and is used in medicine as a culture agent in the production process of antibiotics. High-purity ammonium dihydrogen phosphate is used to manufacture ADP and RTP crystal raw materials. Sodium dihydrogen phosphate is used in biopharmaceuticals for low-phosphate rickets to supplement human blood phosphorus content. In PC/PBT modified plastics, it is used as a lipid exchange agent (inhibitor). Barium dihydrogen phosphate is used in barium-based metal phosphating solutions in the field of metal surface treatment. Titanium pyrophosphate can make the melting process more stable in phosphate glass, and can improve the melting performance of the glass. It can reduce high-temperature viscosity, increase low-temperature viscosity, and has a fluxing effect and is non-volatile. Boron phosphate is used in phosphosilicate optical glasses, as thermally stable pigments, ceramic materials, and decondensation electrolytes for fuel cells.
