There are two types of graphite
Natural graphite and artificial graphite can be used for very different purposes. Natural graphite is mined and traditionally used for refractories as a substitute for asbestos, and of course for pencils. More recently it is used in batteries for electric vehicles.
Artificial graphite is made from pitch and coke particles. It is commonly used as electrodes in electric arc furnaces, moderators in nuclear power stations, micro-circuits on silicon chips and semiconductors. Artificial graphite can also be used in electric vehicle batteries!
Graphite can be found in volcanic vents
Natural graphite is a mineral created when carbon is subjected to heat and pressure in the Earth's crust and upper mantle. Pressure of around 75,000 psi and temperatures from 750 degrees Celsius are needed to produce graphite.
Most of the natural graphite found at the Earth's surface today was formed at convergent plate boundaries. This is where shales and limestones were subject to the heat and pressure of regional metamorphism, producing marble, schist, and gneiss that create tiny crystals and flakes of graphite.
It could survive a chemical attack
Graphite is a refractory material, meaning it is resistant to heat, pressure – or a chemical attack! Graphite was used to hold molten metal before the 1900s, and has since been used in defence. In fact, the UK's Kendal Graphite Mine shows an invoice for the supply of Graphite crucibles for cannonball production to the Napoleonic armoury.
Natural graphite is still used to hold and cast molten metals. Small crucibles can be used for gold and silver, and larger ones can be used for exotic metals. Graphite's refractory properties also cause it to be used as gaskets for high-temperature seals.
Graphite and diamonds are alike
Graphite and diamonds have more in common than many may think! They are both polymorphs, which are minerals that have the same chemical composition (in this case, carbon), but different crystal structures.
In graphite, carbon atoms are linked in hexagonal sheets that resemble chicken-wire fencing. These sheets slide over each other easily, which links to graphites lubricating properties. In diamond, carbon atoms are linked in an infinite pattern of tetrahedra (four-cornered pyramids), making them very strong.
Graphite can conduct electricity
Did you know that graphite is the only non-metal that can conduct electricity? This is because of its delocalized electrons, which move through the hexagonal molecular structure. This creates high electrical conductivity and high thermal conductivity.
Due to this property, graphite is used to transmit the huge amount of power required for electric arc furnaces. Power can be conducted through the electrode to the tip of the furnace, without heating the electrode itself. Moreover, graphite hot zones are used in vacuum furnaces to maintain a constant and controlled environment. This gives greater reliability and consistency when heat treating components for industries such as aerospace.
It can lubricate
The individual layers of hexagonal molecular structure in graphite are loosely attached to each other, meaning that one layer will easily slide over the other. Graphite bearings can replace oil and grease, which would decompose at high temperatures and lead to early bearing failures.
Lubricating graphite bearings can take high loads and are light weight, making them perfect for aeroplanes. They can keep the weight down of the planes, making them much more efficient for flight.
Graphite is used for nuclear applications
Graphite bricks are used at the centre of the entire UK's Advanced Gas-Cooled Reactors (AGRs). The bricks are a crucial safety function, working as neutron moderators which help the nuclear reactor to keep going and stay controlled.
Each reactor core is 10 metres high and weighs 1400 tons – equivalent to 110 double-decker buses. The graphite bricks are an important part of this structure, slowing the speed of neutrons and providing the structure that CO2 gas flows through.
Graphite can save the planet
Graphite manufacturing is renowned for being highly energy-intensive, with the process for one tonne of graphite requiring enough energy for 1.5 million mobile phone charges. We recover used and damaged electrodes and recondition them into green graphite electrodes. This energy-efficient process produces 99% less carbon emissions than the manufacturing process of new graphite electrodes and stops thousands of tonnes of graphite from being sent to landfill sites.
Cleaning Methods For Graphite Plates
Graphite plates have excellent conductivity, heat transfer, heat resistance, and good organic chemical reliability, making them widely used in industries such as metallurgy, chemical engineering, and electrochemistry. However, how should they be cleaned after use?
Take out the graphite plate that has been soaked for 30 minutes from the soaking solution, place the electroplating equipment flat on a wooden frame, and rinse the surface of the equipment with 240 # -320 # water sandpaper. When wiping, hold the positive electrode plate with one hand and gently press the sandpaper with the other hand. Rinse with tap water until the dirt is removed, and then clean the conductive part of the hook with sandpaper. After cleaning, rinse the entire equipment with flowing water and check if there are any stains on the surface. If there are any, clean it again, then empty the cleaning tank, rinse it with tap water, put it in pure water, soak it in pure water, and clean the equipment. After production, hang it on the anode rod and cover it with the anode rod cover.
One thing to note is to wear an apron, rain shoes, gloves, and safety helmet before cleaning. Remember to wash the gloves with water, acid, or water before allowing them to work. Add 109 sodium hydroxide solution to the cleaning tank prepared for cleaning equipment. Open the anode rod cover plate, gently present the graphite plate from the anode rod with both hands, and transfer it to the graphite cleaning tank for soaking for 30 minutes.
After cleaning, please drain the cleaning tank, clean it with drinking water, and then soak it in pure water. This needs to be hung on the pole during production.
During the entire cleaning process, it should be handled with care to prevent equipment breakage. When extracting or installing equipment, remember to enter and exit vertically and do not touch the anode plate; When extracting or installing anode plates, production is strictly prohibited to ensure safety.
Graphite Plate Fault Maintenance Method
For different graphite plate fault types, maintenance methods are also different. The following are some common graphite plate fault maintenance methods:
Crack repair
For minor cracks, repair can be done by applying adhesive to the crack. If the crack is more serious, it is necessary to replace the damaged part or the whole piece.
Deformation correction
For graphite plates with light deformation, it can be corrected by mechanical pressure. If the deformation is severe, it may be necessary to replace the graphite sheet as a whole.
Ablation treatment
In high temperature environment, the ablation of graphite plate is inevitable. In order to extend the service life of the graphite plate, the surface of the graphite plate can be coated with high temperature resistant coating to reduce the degree of ablation.
Troubleshooting of the control system
If the control system is faulty, check the hardware and software of the control system to ensure that the parameters are correctly set and the system runs stably. The control system can be inspected and maintained by regular maintenance and testing.
