ball milling of graphite

The ball milling of graphite in the presence of a liquid leads to very thin, well-crystallized and anisometric particles. In the presence of water, the graphite particles are covered by Fe 2 O 3 (maghemite) formed by the oxidation of the ferrous alloy coming from the milling tools. Effect of extended ball milling on graphite

2018-5-21 · However, ball milling for extended period produces defects and damages the graphite structure rendering it useless for dispersion in lubricants. Studies are made on the effect of ball milling on the structure and defect generation. Pierard et. al. studied the effect of ball milling on the structure of single-walled carbon nanotubes.

Effect of milling time on carbothermic reduction of ilmenite

2015-12-29 · milling parameters, etc. GUPTA et al [7] observed that different types of ore also had significant influence on the reduction degree of ilmenite. However, the effect of ball milling parameters on the reduction process had rarely been reported. Therefore, the aim of the present work is to investigate the effect of milling time on ilmenite reduction.

Effect of Milling Time on the Synthesis of In-situ Cu-25

This paper presents a study on the effect of milling time on the synthesis of Cu-WC nanocomposites by mechanical alloying (MA). The Cu-WC nanocomposite with a nominal composition of 25 vol.% of WC was produced in-situ via MA from elemental powders of copper (Cu), tungsten (W), and graphite (C).

Graphite has been milled for up to 1000 h in a laboratory scale tumbling ball mill under vacuum. Raman spectroscopy of the powders indicated the increasing dominance of D-type graphitic sp 2 bonding over G-type bonding with increasing milling time. Diamond-like sp 3 bonding and possibly fullerene-like bonding also became evident after milling ...
