Direct Laser Synthesis of Fe<sub>2</sub>O<sub>3</sub> Modified TiO<sub>2</sub> 2024 Access copy available to the general public Unrestricted A very fast, selective CO2 laser line scan direct synthesis method is presented and has been applied here to study phase and defect formation within an irradiated mixture of powdered oxides, as a proof‐of‐principle. A nominal composition interval of 0&lt;x&lt;0.03 was conveniently chosen for the TiO2+xFe2O3 system herein reported. X‐ray diffraction analyses were used to determine the main crystalline phase composition. Thus, for 3 % mol. Fe2O3, pseudobrookite crystals were found to coexist with rutile‐type MO2‐δ (M=Ti, Fe) with extended defects. These are composed mainly of (121)r and (132)r crystallographic shear planes (CSP‘s), where r subindex refers to the rutile subcell. For samples with a lower Fe2O3 content (2, 1, 0.5 % mol) only iron‐doped rutile phases were observed, with complex microstructure arising from the presence of multi‐twinned (011)r and (110)r crystals and isolated and/or ordered CSP‘s at short length scale. The diverse microstructures observed in the CO2 laser produced samples correlate with the conditions imposed during the laser treatment, which include intrinsically high solidification rates and steep temperature gradients. info:eu-repo/grantAgreement/ES/DGA/T54-23R info:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-113034RB-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 1.0 2024 CHEMISTRY, INORGANIC & NUCLEAR 39 / 43 = 0.907 2024 Q4 T3 0.292 2024 Inorganic Chemistry 2024 Q3 2.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gómez-Herrero, A.
