Ceramic materials,with excellent high-temperature resistance, wear resistance, and corrosion resistance, are widely used in aerospace, electronics, machinery, and other fields. Recent trends focus on high-performance, multifunctional, and intelligent development. SEM plays a vital role in ceramic research by enabling observation of microstructure, grain size, and morphology; analysis of impurity distribution and fracture surface characteristics. When combined with energy-dispersive X-ray spectroscopy (EDS), qualitative and quantitative elemental analysis could be conducted. It provides crucial technical support for optimizing ceramic performance and developing new ceramics.
