  • Barium metaphosphate powder is an inorganic powder with the molecular formula Ba(PO3)2. It is a colorless solid that is insoluble in water. A number of hydrated forms are known which are actually cyclic metaphosphates, Ba2(P4O12) • 3.5H2O, Ba3(P3O9)2 • 6H2O.
Applications
The combination of sodium and barium polyphosphate forms a low-melting glass with a high coefficient of thermal expansion. The melting point of the glass increases with barium content. This glass makes seals with low melting metals like aluminium (melting point 650 °C). Normal borosilicate glasses soften above the melting point of aluminium. This mixture is prepared by heating a mixture of diammonium phosphate, sodium carbonate, and barium carbonate.
