Tego Magnan powder ball-milled powders

Fig. 2.32 DSC curves for the as-received MgH2 (Tego Magnan) and ball-milled MgH2 powders (IMP2 single magnet), (a) As-received commercial MgH2. Milled for (b) 15 min, (c) 1 h, (d) 10 h, (e) 25 h, (f) 50 h, (g) 75 h, and (h) 100 h in hydrogen (heating rate 4°C/min) [6]...

Fig. 2.33 DSC hydrogen desorption temperatures vs. particle size for as-received and ball-milled Tego Magnan powder, (a) Onset temperature (T ) and (b) low-temperature (LT) and high-temperature (HT) DSC peaks. Numbers beside data points indicate grain (crystallite) size of the P-MgH phase. Standard deviation bars for the particle size (BCD) are omitted for clarity [6]...

Fig. 2.48 DSC traces of Tego Magnan MgH powder doped with m- and n-Ni, and (a) mixed for 1 h without milling (no steel balls) and (b) mixed for 1 h with Tego Magnan MgH which was premilled for 20 h (heating rate 4°C/min argon flow rate 25 ml/min)...
