In shock-compression measruement on solids, it is important to use controlled, high-quality specimens and to use high-capability measurement apppratuses. We have been investigating the shock-yielding property, high-pressure phase transition, equation of state, etc. of ceramics, minerals, semiconductors, etc., through shock-wave measurements. In this report, at first, the improved measruement methods combined with the keyed-powder gun used in our studies are described. In the next, the recent studies on selected good quality ceramics (ZrO2, Si3N4, AIN, B4C) are reviewed. The typical effects of shock compression on yielding property and phase transition of ceramics are shown, and the yielding mechanism and the correlation with material charcterizations are discussed.
