Description
| - Coefficients of hydrogen diffusion in Mg2NiH4 (DI), MgH2 (DM), and in (Mg + Mg2Ni)-H eutectic (DE) were measured in the temperature interval 449–723 K. Experimental material was prepared by two techniques: by melting and casting and by ball-milling and compacting into pellets. Hydrogen charging was carried out from the hydrogen gas phase at high temperature and pressure. The Mg2NiH4 pellets were prepared in different regimes resulting either in a structure with a high fraction or with a low fraction of twinned low-temperature phase LT2. It was found that the LT2 slows down the hydrogen desorption rate considerably.

- Koeficienty difúze vodíku v Mg2NiH4 (DI), Mg2H (DM) and v eutektitu (Mg+Mg2Ni)-H (DE) byly měřeny v teplotním intervalu 449-723 K. Experimentální materiál byl připraven dvěma metodami: tavením a odlitím a kulovým mletím a kompaktováním do tablet. Nabíjení vodíkem probíhalo z plynné fáze při vysoké teplotě a tlaku. Tablety Mg2NiH4 byly pžipraveny v různých regime, což vedlo buď velkému nebo malému podílu frakce dvojčaté nízkoteplotní fáze LT2. Bylo zjištěno, že LT2 významně snižuje desorpci vodíku. (cs)
