Powder properties of hydrogenated ball-milled graphite

Abstract. Ball milling is an effective way of producing defective and nanostructured graphite. In this work, the hydrogen storage properties of graphite, ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0–40 h), were investigated by TGA-Mass Spectrometry, XRD, SEM and laser diffraction particle size analysis.

Graphite Powder an overview ScienceDirect Topics

The high hydrogen storage in a ball-milled graphite was early reported by Orimo and co-workers. They measured a 7.4 wt% hydrogen uptake by ball-milling graphite under a hydrogen atmosphere for 80 h [28]. High storage capacities of ball-milled graphite were also reported and confirmed by other groups [29–32].

Synthesis of graphene oxide from graphite by ball milling

Nov 01, 2020· Planetary ball mill Retsch PM100 was operated at 300 rpm. Vessel for the ball milling was a stainless-steel jar of 50 mL volume. 4.00 g of graphite powder Gr (Alfa Aesar, 99%) was mixed with 6.04 g of potassium perchlorate KClO 4 (Fisher Scientific 99%) and 20.0 mL of deionized water (DI). Powder to balls ratio was 1:20.

Synthesis of novel CuSn10‐graphite nanocomposite powders

The samples were milled at different graphite particles weight percentages (0, 1, 3 and 5 wt%), milling times (0.5, 1, 2, 5, 8, 12 and 24 h) and balls‐to‐powder weight ratio (10:1). The other parameters applied were: ball diameter (10 mm) and speed (400 rpm), respectively.
