Overview

How graphite is used in the chemical and petrochemical

Many processes in the chemical industry involve the pumping, stirring and transportation of corrosive, toxic or explosive products. The pumps used have rotating shafts, which must be sealed to keep out gases or fluids. Applications: Vacuum pumps, turbines, compressors, process pumps. Why graphite? Resistant to corrosion/chemicals, resistant to wear over time, long service life. Foils / Sheets

Si–graphite composites as anode materials for lithium

The mechano-chemical milling and the rotational impact blending methods are applied to synthesize two types of Si–C composites. Graphite powders having Si on the surface (type A) is synthesized by mechano-chemical milling using the pitch as a binder. Si embedded inside the graphite particle (type B) is synthesized by rotational impact blending. The loading level of Si is about 20 wt% for

Electrochemical machining Wikipedia

Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and
