Precision processing and packaging process of alumina ceramics

Precision processing and packaging process of alumina ceramics

Some alumina ceramic materials with high precision requirements still require precision processing after sintering.

Products that can be used as artificial bones require a high surface finish, like a mirror, to increase lubricity.

As the Hardness of alumina ceramics is high, it is necessary to finish them with harder grinding and polishing brick materials.

Such as SIC, B4C, or diamond. Usually, grinding is carried out step by step from coarse to fine abrasive, and the final surface is polished. Generally,<1 can be used μ Grind and polish with m micron Al203 micro powder or diamond paste.

In addition, laser processing and ultrasonic processing grinding and polishing methods can also be used.
