Controlled Oxidant-to-Fuel Ratios for Synthesis of Inorganic Hematite Pigment (α-Fe2O3) Using Solution Combustion Method with 6-Aminohexanoic Acid as Fuel
Abstract
In this study, α-Fe2O3 was synthesized by solution combustion method using 6-aminohexanoic acid (AH) as a fuel and with different oxidizer-to-fuel ratios (Φ) of 0.6, 0.8, 1.0, 1.2, and 1.4. The as-prepared powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), and UV–Vis spectroscopy. The results showed that the Φ ratio played a crucial role in determining the crystallinity and purity of the powders of α-Fe2O3. The α-Fe2O3 powder synthesized at an Φ ratio of 0.6 exhibited phase purity of hematite. This study demonstrates the importance of controlling the Φ ratio in the synthesis of α-Fe2O3 which could be used as an inorganic pigment in paints.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
