The measurement of the temperature history of a powder during the shock compaction process requires a very fast measuring principle. Since the response time of normal thermocouples is too slow for the extremely fast temperature changes occurring in the shock compression of powders, here thermocouples formed by the powder to be compacted are used. The temperature measurements are performed in the cylindrical configuration. Copper and constantan powders are used in the development of the measuring technique. This resulted in measurements of the temperature history in these metallic materials. To be able to investigate whether the temperature history during the shock compaction of ceramics differs from that of metals, two ceramic materials TiB<SUB>2</SUB> and WC) were selected to be used as a powder thermocouple for future work.
