Effect of Ammonia on Preparation of Ammonium Polyphosphate

Advanced Materials Research, 2011
Ammonium polyphosphate (APP) was prepared by process of diammonium hydrogen phosphate at different ammonia atmosphere. XRD techniques were used to characterize the crystalline form of this product. Results showed that ammonium had significant effect on the crystalline form of prepared ammonium polyphosphate.

Proton conductors based on ammonium polyphosphate

Solid State Ionics, 1995
Abstract This study is an attempt to prepare proton conductors based on ammonium polyphosphate (NH 4 PO 3 ). The base material itself is almost an insulator, but becomes appreciably proton-conductive by thermally decomposing NH 4 PO 3 to HPO 3 . The NH 4 PO 3 -HPO 3 mixture obtained has the maximum conductivity of 5 × 10 −3 S/cm at 300 °C, but is ...

Effect of zinc borate on the thermal degradation of ammonium polyphosphate

Thermochimica Acta, 2007
Abstract The thermal behaviour of a mixture containing an ammonium polyphosphate based compound (AP760) and zinc borate (ZB) is investigated. After an investigation of the degradation of the pure components, the interactions between them are examined by thermogravimetry.

Ammonium polyphosphate/montmorillonite nanocompounds in polypropylene

Journal of Applied Polymer Science, 2010
AbstractAmmonium polyphosphate (APP)/montmorillonite (MMT) nanocompounds were prepared. The crystal forms and morphologies of the nanocompounds were studied by XRD, FTIR, SEM, and TEM. The APP/MMT nanocompounds were applied to intumescent flame‐retarded polypropylene (PP) composites. The PP composites were studied by using oxygen index measurements, UL‐

Effect of Temperature on Preparation of Ammonium Polyphosphate

Advanced Materials Research, 2013
Ammonium polyphosphate (APP) with crystalline form II is usually synthesized in temperature 280-3100C, APP with crystalline form V is usually synthesized in temperature 340-3500C. By process of diammonium hydrogen phosphate, the effect of temperature on crystalline forms of APP was studied and discussed in detail.

Characteristics of magnesium polyphosphate cements derived from ammonium polyphosphate solutions

Cement and Concrete Research, 1983
Magnesium polyphosphate cement pastes prepared by mixing MgO powder and ammonium polyphosphate (AmPP) solutions yielded early strengths of 2000 psi (13.78 MPa) at an age of 1 hr. The major reaction products responsible for the initial strength development at room temperature were found to be ternary phases of NH4MgPO4·6H2O and Mg3(PO4)2·4H2O.

Ammonium Polyphosphate as a Source of Phosphorus and Nonprotein Nitrogen for Monogastrics

Journal of Animal Science, 1981
Ammonium polyphosphate (APP) was substituted for 0, 50 and 100% of the P supplied by defluorinated rock phosphate (DRP) in corn-soybean meal diets for growing rats and growing-finishing (G-F) pigs. The diets were formulated to contain 10% protein, .75% Ca and .60% P. Two-thirds of the P in the control diet was supplied by DRP. Replacement of 50 or 100%
