Due to its outstanding physical, chemical, and mechanical properties, it is widely used in industrial, electronic, medical, and other fields. Preparation Process 1. Raw Material Preparation: Purification of bauxite or chemical synthesis to produce high-purity alumina powder. 2. Forming: Dry pressing (simple shapes) Slip casting (complex shapes) Isostatic pressing (high-performance components) 3. Sintering: High-temperature densification (1600\u00b0C\u20131800\u00b0C) via atmospheric or hot-press sintering. 4. Post-processing: Precision grinding and polishing (high processing costs due to extreme hardness). Classification (by Al\u2082O\u2083 content) Standard alumina ceramics: 75%\u201395% Al\u2082O\u2083, used for general corrosion-resistant and wear-resistant components.
