Two frit ceramic materials were prepared from minerals (phosphate and feldspar) and other low-cost materials (bones and glass cullet). These powders can be used in agriculture as fertilizers since they are able to release the nutrient elements at a low rate. The above materials were characterized by X-ray Diffraction, Photoluminescence Spectroscopy, Scanning Electron Microscopy and Inductively Coupled Plasma Atomic Emission Spectrometry. The dissolution kinetic of macro and micro nutrients, components from frit materials, was also studied. |
