What you should know about artificial graphite

US President recently decided to invoke a Cold War-era defense law to encourage domestic artificial graphite.

Artificial graphite, is similar to polycrystals in crystallography. There are many kinds of artificial graphite, and the production process is very different.

In a broad sense, all graphite materials obtained by carbonization of organic matter and then by high temperature treatment of graphitization can be collectively referred to as artificial graphite, such as carbon (graphite) fibers, pyrolytic carbon (graphite), foamed graphite, etc.

In a narrow sense, artificial graphite usually refers to the use of carbonaceous raw materials (petroleum coke, pitch coke, etc.) with low impurity content as aggregates, coal tar pitch, etc. as binders. Bulk solid materials prepared by processes such as roasting) and graphitization, such as graphite electrodes, isostatic graphite, etc.

There are many forms of artificial graphite, including powder, fiber and block, while artificial graphite in the narrow sense is usually block, which needs to be processed into a certain shape when used. It can be regarded as a multiphase material, including graphite phase converted from carbonaceous particles such as petroleum coke or pitch coke, graphite phase converted from coal tar binder surrounding the particles, particle packing or coal tar tar binder The pores formed after heat treatment, etc. Generally speaking, the higher the heat treatment temperature, the higher the degree of graphitization. The degree of graphitization of industrially produced artificial graphite is usually less than 90%.

Compared with natural graphite, artificial graphite has weaker heat transfer performance, electrical conductivity, lubricity and plasticity, but artificial graphite also has the advantages of better wear resistance, corrosion resistance and low permeability than natural graphite.

The raw materials for making artificial graphite mainly include petroleum coke, needle coke, pitch coke, coal tar, carbon microspheres, etc.; its downstream products mainly include graphite electrodes, prebaked anodes, isostatic graphite, high-purity graphite, nuclear graphite, thermal switch, etc.

The application of artificial graphite products is mainly reflected in the following aspects:

1. Graphite electrode: a graphite electrode made of petroleum coke and needle coke as raw materials and coal tar as a binder, which is calcined, batched, kneaded, pressed, roasted, graphitized and machined. The electric arc is used to release electric energy to heat and melt the charge, which is widely used in electric furnace steel, industrial silicon, yellow phosphorus and other equipment.

2. Prebaked anode: It is made of petroleum coke as raw material and coal pitch as binder. It is made by calcining, batching, kneading, pressing, roasting, dipping, graphitization and machining. It is generally used for the electrical conductivity of electrolytic aluminum equipment. anode.

3. Bearings, sealing rings: equipment for conveying corrosive media, piston rings, sealing rings and bearings made of artificial graphite are widely used, and there is no need to add lubricating oil during operation.

4. Heat exchangers and filters: Artificial graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability. It is widely used in the chemical industry to make heat exchangers, reaction tanks, absorption towers, filters and other equipment.

5. Special graphite: using high-quality petroleum coke as raw material, coal tar or synthetic resin as binder, through raw material preparation, batching, kneading, tableting, crushing, re-kneading, molding, multiple roasting, multiple impregnation and purification and graphitization and machining, generally including isostatic graphite, nuclear graphite, high-purity graphite, etc., used in aerospace, electronics, and nuclear industries.

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.  

Matviyenko also noted that Europe currently lacks politicians who can make independent decisions.  She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.

On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security. 

Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain artificial graphite are expected to continue to be influenced by international situations.
