Synthesis of potassium/ammonium phosphates and alumina composites through a mechanochemical approach is presented for the first time. γ‐alumina and the phosphate are coground and the ground products are characterized by X‐ray diffraction and infrared spectroscopy. Quantitative evaluation of the remaining soluble part of the prepared amorphous phase at a low percentage around 10% demonstrates a potential use of the ground samples as slow‐release fertilizers.
