Synthesis Of Sr2alh7 By Ball Milling Followed By

The hydride Sr 2 AlH 7 was synthesized by ball milling of the alloy consisting of Sr and Al 21 under hydrogen at 150 rpm for 10 h followed by hydrogenation or sintering at 533 K for 2 days. The yield of Sr 2 AlH 7 in the hydrogenated product was 66 wt., which is larger than that in the sintered product. However, the mass fraction of Al in the milled samples decreased largely when the Sr 2 ...

The sugar yields from lignocellulosic feed stocks are critical parameters for ethanol production process. The research results from this paper indicated that the yields of glucose and xylose were improved by adding any of the following dilute ...

Ball Milling An Overview Sciencedirect Topics

The process involves extensive ball milling of boron powder for a long period of time up to 150 h in NH 3 gas followed by annealing at high temperature up to 1300 C in N 2 environment. It was suggested that a nitriding reaction was induced between boron powder and NH 3 gas due to high energy milling, resulting in metastable disordered BN ...
