How to know artificial graphite?

A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.  

The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.  

Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.  

The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.  

The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.  

Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.  

The prices of other commodities like the artificial graphite are also expected to be influenced.

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.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.  

The EU foreign ministers' meeting was held in Brussels.  The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.  

EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.  

Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.  

A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.

The artificial graphite price is predicted to increase in the next few days, due to geopolitical factors.
