Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on Artificial graphite prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
In a broad sense, all graphite materials obtained by organic carbonization and then graphitization at high temperature can be called artificial graphite, such as carbon fiber, pyrolytic carbon, foamed graphite, etc. In the narrow sense, artificial graphite usually refers to the block solid material obtained through the processes of batching, kneading, molding, carbonization and graphitization, using carbonaceous raw materials with low impurity content as aggregates, coal tar pitch, etc. as binders. Such as graphite electrodes, isostatic graphite, etc.
What is Production method of Artificial graphite ?
There are many ways to manufacture artificial graphite. The common method is to use powdered high-quality calcined petroleum coke as the main raw material, add asphalt as a binder, and then add a small amount of other auxiliary materials. After the various raw materials are combined, they are pressed into shape, and then treated in a non-oxidizing atmosphere at 2500-3000 ° C to make them graphitized.
What is the main characteristics of Artificial graphite ?
Natural graphite: The crystal development is relatively complete, the degree of graphitization of flake graphite is more than 98%, and the degree of graphitization of natural microcrystalline graphite is usually below 93%.
Artificial graphite: The degree of crystal development depends on the raw material and the heat treatment temperature. 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%.
Natural flake graphite: It is a single crystal with a relatively simple structure and only has crystallographic defects (such as point defects, dislocations, stacking faults, etc.), and exhibits anisotropic characteristics on the macroscopic level. The grains of natural microcrystalline graphite are small, the grains are disorderly arranged, and there are pores after removal of impurities, which shows isotropy on the macroscopic level.
Artificial graphite: It can be regarded as a multi-phase material, including graphite phase transformed from carbonaceous particles such as petroleum coke or pitch coke, graphite phase transformed from coal tar binder surrounding the particles, particle accumulation or coal tar pitch. The pores formed by the binder after heat treatment, etc.
physical form Natural graphite: usually exists in the form of powder and can be used alone, but it is usually used in combination with other materials.
Artificial graphite: There are many forms, 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.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Artificial graphite, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the Artificial graphite chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.
The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment. For more information about Artificial graphite, please feel free to contact us.
