Hydrogen Absorption of LaFe10.9Co0.8Si1.3 Compound under Low Hydrogen Gas Pressure

Bin FU, Jie HAN

Abstract


The effects of hydrogen absorption on structure, Curie temperature and phase transition property for the LaFe10.9Co0.8Si1.3 compound are investigated by X-ray diffraction (XRD) and differential scanning calorimeter (DSC) in a 1-atm H2 gas. The original compound and hydride present cubic NaZn13-type structure. The Curie temperature of LaFe10.9Co0.8Si1.3 shifts from 277K to 346K and temperature range of the phase transition becomes wider significantly after hydrogen absorption.
