Description

The characterization of the material structure has three main tasks: component analysis, structure determination, and morphology observation. In addition to traditional chemical analysis techniques, chemical composition analysis of materials includes mass spectrometry, ultraviolet, visible, infrared spectroscopy, gas, liquid chromatography, and nuclear magnetic resonance. The characterization of the material structure is still dominated by diffraction methods. The diffraction methods mainly include X-ray diffraction, electron diffraction, neutron diffraction, Musberg spectrum, ?-ray diffraction, and the like. Morphology observation mainly relies on the microscope, which is a popular method for observing materials on the micrometer scale. Scanning electron microscopy and transmission electron microscopy advance the observed dimensions to sub-micron and sub-micron levels.
