LaNi sub 5 hydride formation. The effect of the thermal conductivity of the holder on the kinetics
Samples of LaNi sub 5 H sub 6 were synthesized in a high-pressure thermobalance; several sample containers were used, differing in shape, lateral surface and thermal conductivity. Comparative studies were made using thermal analysis. Experimental results show that a large lateral surface of the samp...

Zusammenfassung: | Samples of LaNi sub 5 H sub 6 were synthesized in a high-pressure thermobalance; several sample containers were used, differing in shape, lateral surface and thermal conductivity. Comparative studies were made using thermal analysis. Experimental results show that a large lateral surface of the sample holder improves the heat transfer. In the case of the other holders, the temperature variations are important and experiments cannot be carried under isothermal conditions. |
