Gradient transducer application in heat metering at temperatures up to 1300 K has no world analogs because up to date gradient heat flow transducers (GHFT) have been generally made from monocrystalline bismuth. However GHFT from bismuth are functional only till the melting point of bismuth (541 K). Different metallic layered composites have been tested, both compacted and porous. Volt-watt sensitivity of the gradient heat flow transducers at 300 K for different metallic layered composites changed from 0,02 to 0,4 mV/W.
