Variation of mechanical property for advanced ceramics is one of the serious problems. We have developed the various optical methods to examine the macro defects in ceramics before and after sintering. There are lots of crack-like macro-defects in ceramics. Their origins of macro defects were formed even after compaction of granules. The macro defects in ceramics successfully explained the strength variation by strength test simulation based on defects distribution. Micro x-ray computer tomography has been developed as a powerful tool for measurement of macro-defects, recently. Their image will show us 3 dimensional structures for various materials.
