Abstract
Barium-ammonium polyphosphate (BaNH4(PO3)(3)), bismuth-ammmonium cyclo tetraphosphate (BiNH4P4O12), and titanium-ammonium tetraphosphate (Ti( NH4)(2)P4O13) have been synthesized in the melt of ammonium polyphosph ate (NH4PO3). The prepared phosphates were characterized by chemical a nalysis, thin layer chromatography, and X-ray diffraction of powders. BiNH4P4O12 was found to crystallize in the cubic system, space group < I(4)over bar 3d> with the unit-cell parameter a = 15.105(2) Angstrom. Thermal decomposition behavior of the phosphates was studied by thermo gravimetry and crystalline products of degradation were identified. (C ) 1996 Academic Press, Inc.
