Graphite & Carbon uses in Industrial Applications

How graphite is used in manufacturing and electrical discharge machining (EDM)

Why graphite is the ideal material

TYPE OF PRODUCT

APPLICATION

Rupture discs

Designed to protect high-pressure equipment and systems from over-pressurising or causing potentially damaging conditions.

Applications: Safety devices, pressure protection devices

Why graphite? Won’t corrode, can withstand high temperatures, can be used in harsh conditions without impacting performance

Discs for X-ray anodes

An anode is the rotating bevelled disc inside an X-ray tube where the X-rays are produced.

Applications: X-ray machines

Why graphite? Good at conducting heat, lightweight, resistant to wear

Roughing electrodes

Used in certain machining processes to transmit the electrical charges and remove metal from the workpiece to bring about the desired shape.

Applications: Electrical discharge machining (EDM)—Passing an electrical current between two electrodes separated by a dielectric liquid to create an intensely hot spark which can then be used to shape a piece of material. Read more about EDM here.

Why graphite? High melting point, resistant to high temperatures, easy to machine

Carbon bricks

Strictly speaking, carbon bricks aren’t graphite. Graphite is used to make complex-shaped parts for chemically resistant linings, which are used alongside or in place of carbon bricks in furnaces and other high-temperature vessels.

Applications: Furnaces, kilns, incinerators

Why graphite/carbon? Chemically inert, able to withstand high temperatures, resistant to thermal shock

Chemically resistant linings

Designed to protect the outer lining of a vessel from aggressively corrosive acidic/alkaline substances.

Graphite is used to make complex-shaped parts for chemically resistant linings, which are used alongside or in place of carbon bricks in furnaces and other high-temperature vessels.

Applications: Baths, reaction vessels, scrubber stages in waste incineration plants, vessels in sulphuric acid production plants

Why graphite/carbon? Resistant to extremely high concentrations of acids, solvents and alkaline solutions (providing there is no oxidation), chemically inert, low porosity

Heating elements

Components of high-temperature systems.

Applications: Industrial furnaces, vacuum furnaces, UHV heaters

Why graphite? Resistant to wear, resistant to oxidation, can withstand extremely high temperatures, resistant to thermal shock, chemically inert

Susceptors

Induction heating is a method used to heat metals (including precious metals, brass, aluminium and steel) or semiconductors such as silicon carbide.

The process involves heating a susceptor, typically made of graphite, which then transfers the heat to the metal or semiconductor by radiation or conduction.

Applications: Heating fluids, plastic sealing, manufacturing thermoplastic composites, cap sealing

Why graphite? Good conductivity, resistant to high temperatures, easy to machine

Insulation felts

Insulating a furnace with soft graphite felts stabilises the temperature inside the furnace (creating a more constant atmosphere) and allows the furnace to both heat up and cool down more quickly.

Applications: Induction furnaces, furnaces using a cylindrical-style hot zone, vacuum furnaces

Why graphite? Conductivity of heat, resistant to high temperatures, lightweight
