Abstract
Silicon nitride granule and green body were made transparent by immersion liquid which have a refractive index close to that of silicon nitride. Their internal structures were examined directly by means of optical microscope. Sharp void spaces existed even in the green body which was isostatically pressed at 600MPa. Present method is very useful for studying the processing of ceramics, because it gives us more detailed information than other methods.
