What is the difference between natural graphite and artificial graphite?

Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the natural graphite still face uncertainty.

Given that what is prepared from natural graphite is usually artificial graphite in the narrow sense, this paper will only analyze and discuss the differences and links between natural graphite and artificial graphite in the narrow sense.

Crystal structure

The crystal development of natural graphite is relatively complete, the graphitization degree of natural flake graphite is usually above 98%, and the graphitization degree of natural microcrystalline graphite is usually below 93%.

The degree of crystal development of artificial graphite depends on the raw material and the heat treatment temperature. Generally speaking, the higher the heat treatment temperature, the higher the degree of graphitization. At present, the degree of graphitization of artificial graphite produced in the industry is usually less than 90%.

Organizational structure

Natural flake graphite is a single crystal with a relatively simple structure, with only crystallographic defects (point defects, dislocations, stacking faults, etc.), and macroscopically showing anisotropic structural characteristics. The grains of natural microcrystalline graphite are small, the grains are disorderly arranged, and there are pores after the impurities are removed, showing the isotropic structural characteristics on the macroscopic level.

Artificial graphite can be seen as a multi-phase material consisting of a graphite phase transformed by carbonaceous particles such as petroleum coke or pitch coke, a graphite phase transformed by a coal bitumen binder encapsulated around the particles, particle accumulation, or pores formed after heat treatment of coal tar binder, etc.

Physical form

Natural graphite usually exists in powder form and can be used alone, but is usually used in combination with other materials.

There are many forms of artificial graphite, including powder, fiber, and block, while artificial graphite in the narrow sense is usually blocked, which needs to be processed into a certain shape when used.

Physical and chemical properties

Natural graphite and artificial graphite have both commonalities and differences in performance. For example, both natural graphite and artificial graphite are good conductors of heat and electricity, but for graphite powders of the same purity and particle size, natural flake graphite has the best heat transfer performance and electrical conductivity, followed by natural microcrystalline graphite and artificial graphite the lowest.

Graphite has good lubricity and certain plasticity. Natural flake graphite has better crystal development, smaller friction coefficient, best lubricity, and highest plasticity, while dense crystalline graphite and cryptocrystalline graphite are second, and artificial graphite is worse.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the natural 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 natural 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 natural graphite, please feel free to contact us.
