General description

Ammonium phosphate dibasic [(NH4)2HPO4], also known as diammonium phosphate (DAP), is used as a fertilizer, and as a fire retardant material.

Application

DAP can be used as:
  • A source of phosphate to synthesize nanophase hydroxyapatite (HaP) crystals in the presence of calcium nitrate and ammonia by wet chemical precipitation method.
  • A reagent in the preparation of Fe3P composite nanorods.
  • Phosphate precursor for the preparation of mesoporous LiFePO4/carbon microspheres by hydrothermal method for lithium-ion batteries.

This paper reports an "all in one" procedure to produce mesoporous, micro-spherical LiFePO₄ composed of agglomerated crystalline nanoparticles. Each nanoparticle is individually coated with a thin glucose-derived carbon layer. The main advantage of the as-synthesized materials is their good performance

A simple and facile wet chemistry route was used to synthesize nanophase hydroxyapatite (HaP) crystals at low temperature. The synthesis was carried out at a pH of 11.0 and at a temperature of 37°C. The resulting samples were washed several
