CALORIMETRIC INVESTIGATION OF HYDROGEN INTERACTION WITH INTERMETALLIC COMPOUNDS AT PRESSURE UP TO 2000 atm

摘要

Investigation of the Ce_(0.8)La_(0.2)Ni_5-H_2 system consisting calorimetric measurements for hydride formation and decomposition and simultaneous measurements of P-C isotherms in the temperature range 333-433 K have been made. The combined instalation includes a heat-conducting Tian-Calvet type calorimeter coupled with high gaseous pressure apparatus which allows measurement of the heat effects up to 2500 atm and demonstrates the possibilities of calorimetry and the choice of the object to be measured.
