چکیده
Lanthanum Magnesium Hexaaluminate (LaMgAl11O19, LaMA) is a promising material for various applications, including thermal barrier coatings, catalysts, and optical materials, due to its unique properties such as high-temperature thermodynamic and structural stability, low thermal conductivity, and good chemical resistance. In this study, the densi-fication of synthesized LaMA powder was investigated using spark plasma sintering (SPS). The effects of SPS on the relative density, mechanical properties, and crystallographic tex-ture were evaluated. The results showed that SPS achieved a high relative density of 97.56 ± 0.25% and a flexural strength of 367± 13 MPa, which is in good agreement with the find-ings of other researchers. Remarkably, X-ray diffraction analysis revealed the development of a strong crystallographic texture in the sintered body, characterized by a significant preferential orientation of the (006) plane (Texture Coefficient = 2.82). Scanning electron microscopy confirmed microstructural rearrangement and grain growth. The formation of this textured microstructure, attributed to the preferential alignment of platelet-like grains under uniaxial pressure during SPS, is a key finding of this work and contributes to the understanding of structure-property relationships in SPS-processed hexaaluminates.
