5.3.3 Strength

The figure for the strength of ceramic materials, [MPa] is statistically distributed depending on the material composition, the grain size of the initial material and the additives, the production conditions and on the manufacturing process. According to the weakest link model, the defect distribution and what is termed the critical defect decide the reliability of the part. For this reason the scatter between batches can be greater than within one batch.
