Synthesis of Sodium Lanthanum Lead Chloride Apatite Structure at High Temperatures abstract
The studied solid-state reaction method was synthesized and characterized by Pb (8-x) Na2Lax (PO4)6Clx compounds with x ranging between 0.0 and 2.0. The synthesis process involved calcination at 830 °C for 60 hours. XRD (X-ray diffraction) analysis performed using a Bruker D8 Advance Difractometer with Cu Kα radiation showed that the apatite-type structure was preserved in all compositions. At the same time, peak position shifts indicated the substitution of La³⁺ ions and expansion of the unit cell. Energy dispersive spectroscopy (EDS) performed using a JEOL JSM-7800F FESEM with INCA PentaFETx3 (Oxford Instruments, England) showed semi-quantitative results that closely match theoretical values. In addition, high-quality morphological structures were obtained. OriginPro 2023 software was used to process the data for this investigation, while phase identification was performed using Match! version 3.12 software with PDF-2 and PDF-4 databases. These data indicate the great potential of the investigated materials for catalytic and electrochemical applications and expand the understanding of the effects of La substitution in apatite-type structures.
