1, Japanese ceramic disk, the particle structure and chemical composition of ceramics are fine, and there is no continuous combination between crystals. Therefore, when impacted by external force, tiny cracks will appear between crystals. These cracks will spread throughout the material and eventually lead to ceramic fracture.

2, Japanese ceramic disk, manufacturing process and conditions of use The manufacturing process and conditions of use of ceramics will also have an impact on its brittleness. In the manufacturing process, ceramics usually need to be fired at high temperature, which may lead to some invisible tiny defects in the ceramic structure.
