Special ceramics are also called craft ceramics or advanced ceramics, and there is no strict definition. It contains a large number of different types of minerals. Alumina ceramics is a ceramic material with alumina (Al₂O₃) as the main body. Definition of high-performance ceramics: "Highly developed, high-strength ceramic materials, mainly non-metallic and inorganic materials, and have certain special functions." Different from ancient ceramics in the industry, it is customary to call it advanced ceramics, but advanced ceramics have a larger scope, and special ceramics can correspond to functional ceramics and structural ceramics in the advanced ceramic classification. Alumina is one of special ceramic powder materials.

Alumina ceramics is a ceramic material with alumina (Al₂O₃) as the main body. Alumina ceramic features: high strength, high impact resistance, abrasion resistance, high hardness, excellent temperature resistance, excellent electronic insulation, strong corrosion resistance, etc. It can be made into various wear-resistant appliances and insulating materials such as various alumina ceramic tiles, linings, lining tubes, lining tiles and wear-resistant balls, and it can also be used in the production of integrated circuits, of course, is it a thin film integrated circuit? It is a thick film integrated circuit.
