An aluminum phosphate powder (AlPO4) was synthesized using a modified Ouzo nanoemulsion technique. Monolithic AlPO4 ceramics were subsequently produced via a field-assisted sintering technique (FAST) at temperatures 1300 °C and 1400 °C. Both the powder and sintered samples were comprehensively characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Structural characterization of the field-assisted sintered samples revealed stabilization of the high-temperature orthorhombic phase, which may have occurred due to the presence of oxygen vacancies. Mechanical and thermal characterizations of the sintered samples were also performed. Across various thermal treatments, the high-temperature orthorhombic phase gradually transformed to a tridymite monoclinic structure due to temperature-induced atomic displacements caused by shifting and tilting of adjacent layers of rigid AlO4 and PO4 tetrahedra. This study reveals that pressure-dependent polymorphism reflects temperature-dependent phase stability, influenced by external energy inputs from the applied current, which modulates structural rearrangements. The results demonstrate that the modified Ouzo nanoemulsion synthesis method is a highly effective technique for producing AlPO4 powders with favorable sintering properties.

To develop microwave absorbers that are thin, lightweight, broad in range, and exhibit high-performance absorption capabilities, it is essential to manage both the composition and the design of the absorbers’ microstructure. The innovative 2D MXene material has garnered significant interest due to its unique layered structure and high specific surface area. In this work, hydrothermal and electrostatic self-assembly methods were employed to create a high-performance absorber. The process involved applying single-layer Ti3C2TX MXene, introducing CoFe2O4 magnetic nanospheres and 1 T/2H MoS2 nanoflowers to prepare a three-dimensional CoFe2O4/MoS2/Ti3C2TX (CMT) nanocomposite. By fully utilizing the excellent magnetic properties of CoFe2O4 and the heterogeneous interface of 1 T/2H MoS2, multiple polarization interfaces were formed, resulting in interfacial polarization loss. Additionally, synthesizing 1 T/2H MoS2 into a flower-like structure enhanced the material’s loss capability through multiple reflections. This distinctive ternary heterostructure exhibited outstanding electromagnetic wave absorption properties. An effective absorption bandwidth (EAB) of 5.52 GHz, spanning 11.2-16.72 GHz, was obtained at a thickness of 2.16 mm, covering a significant portion of the Ku band and part of the X band. Moreover, radar cross-section (RCS) simulations were conducted to further verify the material’s electromagnetic absorption capability. This study offers important perspectives on optimizing the structure and improving the performance of innovation MXene-based absorbers.
