Alumina ceramic polishing technology processing method

Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has become more and more widely used in modern society to meet the needs of daily use and special performance. Alumina ceramics are currently divided into two types: high-purity type and ordinary type.

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. Here is an introduction to the polishing treatment methods of alumina ceramics, there are the following:

1. Using laser processing and ultrasonic processing, grinding and polishing;

2. Use Al2O3 micropowder or diamond paste for grinding and polishing;

3. The method of glazing is required (suitable for products with high requirements for surface smoothness);

4. 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;

5. Because the hardness of alumina ceramic material is relatively good, use diamond, silicon carbide, B4C, which is harder than alumina, to grind from coarse to fine step by step, and in the process of finishing, it is necessary to improve the alumina in advance. The lubricity of the ceramic material surface.
