Abstract
Using a twin system for hydrogen absorption, we have studied heat evolution and high-energy particle generation by D2 and H2 gas absorption into nano-sized mixed oxide powders of palladium and zirconium. We have found very large energy of hydrogen absorption by Pd·Zr oxide compounds exceeding 1.0 eV/D (or H) together with a very high D/Pd loading ratio, exceeding 1.0. The system has been improved to enable time-dependent measurements of the gas flow rate and loading ratio simultaneously with the output heat. It has been revealed that the first phase is divided into two sub-phases; the 1a-phase, where most of the anomalously large output energy is produced with a very high loading, D/Pd ≈ 1.2, and the 1b-phase, where much smaller power is produced as loading increases further by a ratio of about 0.5 with a difference in pressure between deuterium and hydrogen.
