Abstract
Microwave synthesis technology, as an efficient and rapid method for material preparation, demonstrates unique advantages in the field of inorganic materials. Unlike traditional heating methods that rely on thermal conduction and convection, microwave synthesis achieves selective heating through direct interaction between electromagnetic fields and materials, significantly reducing reaction time and enhancing product purity. This study aims to explore the application potential of microwave synthesis technology in the preparation of inorganic materials, particularly its impact on material structure, properties, and morphology. Experiments were conducted using various inorganic material systems, including me tal oxides, composite oxides, and nanomaterials, systematically investigating the effects of microwave power, reaction time, precursor concentration, and other factors on the synthesis process. Results indicate that microwave synthesis can effectively control phase transformation, particle size distribution, and morphological characteristics of materials, exhibiting superior selectivity and controllability at the nanoscale. Compared with conventional methods, microwave synthesis not only drastically shortens the reaction cycle but also improves yield and product quality. Additionally, this technology enables efficient material synthesis at low temperatures, reducing energy consumption and minimizing by-product formation. Innovatively, this study proposes a microwave-assisted in-situ growth mechanism, elucidating the intrinsic relationship between ion migration and crystal growth in microwave fields, providing theoretical insights into the microwave synthesis process. The findings offer new perspectives for developing novel inorganic functional materials, holding significant scientific importance and application value.
