Crystalline Transformation of Ammonium Polyphosphate from Intermediate APP-X to APP-II

Abstract:

Article Preview

Ammonium polyphosphate (APP) is an effective intumescent flame retardant, it has different crystalline forms and therefore, different application. By process of diammonium hydrogen phosphate, the intermediate APP-X in between ammonium polyphosphate form II (APP-II) and form V (APP-V) was found and measured. The transformation process from APP-X to APP-II were studied and discussed. The XRD patterns in this process were discussed in detail so that the crystalline transformation process from APP-X and APP-II can be understood.
