The optimum modified cathode showed a significant improvement of complete …

Graphite material is a kind of conductive material with excellent thermal shock resistance, is an important strategic mineral resources, widely used in iron and steel smelting, aviation, aerospace and other fields. However, the graphite electrode is easy to be oxidized in the air, resulting in a large amount of graphite electrode loss. In this …

The chemical structures of GrCNs was investigated through XRD, FTIR, XPS, and elemental analysis. As shown in Fig. 1 a, the XRD pattern of few-layered graphite presents the (0 0 2) characteristic peak at 26.5° which is assigned to the interlayered stacking [36].Similarly, the (0 0 2) peak ascribed to the interlayered stacking of CN can …

Concentration in mineral processing, also known as ore beneficiation or ore dressing, refers to the process of separating valuable minerals from the gangue or waste material to obtain concentrates. The concentration process involves various techniques, including gravity separation, froth flotation, magnetic separation, etc.

Developing a uniform polymer-based composite filament is a critical factor for a successful 3D process. In this regard, a novel technique for the fabrication of PLA-graphite filament with the potential to be applied to other PLA-based composite filaments was proposed and compared to the solvent casting method.

The effect of PBs on the delamination width and maximum cutting speed in laser cutting of graphite–copper–graphite electrodes was investigated by Huang et al. 31 However, cutting fundamentally differentiates from laser microdrilling as the process is governed by the need to penetrate the copper current collector, which possesses a ...

However, during the last three years, significant process improvements have been made in the direct metalization process based on a patented dispersion of graphite. This paper will describe the technology in detail and present data on the reliability and versatility of the graphite based direct metalization process.

There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total …

This process is based on graphite intercalated compound (GIC) chemistry developed in the field of batteries. One of the most interesting anions for GIC formation is sulphate anion, and intercalation of sulphuric acid into graphite is a well-known process [23,24,25].
