Kiinteäainekemia

Kiinteäainekemia, also known as solid-state chemistry, is a branch of chemistry that deals with the study of solid materials. It focuses on understanding the synthesis, structure, properties, and reactions of solid substances. This field is crucial for developing new materials with specific functionalities, ranging from advanced electronics and catalysts to pharmaceuticals and energy storage devices.

The study of solid-state chemistry involves various analytical techniques to characterize the materials. These include X-ray diffraction (XRD) to determine crystal structures, spectroscopy (e.g., infrared, Raman, NMR) to identify chemical bonds and molecular vibrations, microscopy (e.g., scanning electron microscopy, transmission electron microscopy) to visualize morphology and microstructure, and thermal analysis (e.g., differential scanning calorimetry) to study phase transitions and thermal stability.

Key areas within kiinteäainekemia include the synthesis of novel compounds, often through high-temperature reactions, solid-state diffusion, or sol-gel methods. Researchers explore defects in crystal lattices, as these imperfections significantly influence material properties like conductivity and reactivity. The field also encompasses the study of interfaces between different solids and the behavior of materials under extreme conditions, such as high pressure or temperature. Applications are diverse, including the development of semiconductors, superconductors, magnetic materials, zeolites for catalysis and separation, and advanced ceramics.
