The alkali resistance performance of ceramic bearings is usually evaluated based on their alkali corrosion rate or chemical stability. The performance of different types of ceramic materials may vary in different alkaline media.
Generally speaking, ceramic materials have good alkali resistance in neutral or weakly alkaline environments (pH values between 7-8). Common ceramic bearing materials such as alumina ceramics (Al2O3) and zirconia ceramics (ZrO2) typically exhibit good alkali resistance under these conditions.
However, in strong alkaline environments, the alkali resistance of ceramic materials may be affected to some extent. In this case, it may be necessary to consider other materials, such as pure ceramics or metal materials.
It should be noted that the specific alkali resistance performance is also influenced by factors such as the preparation process, purity, crystal structure, and specific alkaline medium of the ceramic material. Therefore, if you have specific concerns about the tolerance of a certain ceramic material under specific alkaline conditions, it is recommended to consult further with ceramic material manufacturers or relevant experts in the field to obtain more accurate parameter values and evaluation data.
