It has become very common to use
alumina ceramics for thick film integrated circuits. Ceramic materials with alumina (Al2O3) as the main body have good conductivity, mechanical strength and high temperature resistance. It is currently used as a wide range of ceramics.
However, after the alumina ceramic is sintered and cooled, it does not mean the end of product processing. Some products do not meet the application requirements. Therefore, they need to be processed, such as size correction, polishing, etc. In order to let everyone know more clearly, Mingrui Ceramics, a professional manufacturer of alumina ceramics, will give a specific introduction. What are the polishing methods for alumina ceramics?
1. Using laser processing and ultrasonic processing to grind and polish.
2. Use Al2O3 powder or diamond paste for grinding and polishing.
3. The method of glazing is required (suitable for products that require high surface smoothness).
4. Use diamond, silicon carbide, etc., which are harder than alumina, to grind step by step from coarse to fine.
5. The surface of the material is processed by ion implantation. Ion implantation of ceramic is a supplement to the existing toughening mechanism and is a deep processing of the prepared ceramic products.
The polishing treatment method of alumina ceramics must strictly follow the above methods to produce good, excellent and qualified products.
