What is the difference between natural graphite and artificial graphite?

In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco in March 2022, the propane contract price (CP) in March was $895 / ton, up $120 / ton from the previous month, up 15.48% from the previous month and up 43.20% from the same period last year. Butane contract price (CP) in March was 920 US dollars/ton, up 145 US dollars/ton compared with last month, up 18.71% month-on-month, up 54.62% compared with the same period last year; In March, CP in Saudi Arabia rose sharply, giving a strong boost to the international and domestic LPG market. Benchmark LPG prices are higher than a year ago as the economy continues to recover and demand for crude oil continues to repair. According to this trend, the market price of natural graphite will also be affected to a certain extent.

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.

At a regular press conference held by the Ministry of Commerce on March 31, a media question was raised: The COVID-19 outbreak has led to the shutdown of production in many parts of China. What impact will it have on China's foreign trade enterprises as a whole and micro, small and medium-sized foreign trade enterprises?

In this regard, the Spokesperson of the Ministry of Commerce said that the Ministry is closely following the impact of the epidemic on foreign trade enterprises, especially small, medium and micro foreign trade enterprises. As far as we can see, some foreign trade enterprises are affected by the epidemic and are faced with periodic problems in production and operation, logistics and transportation. At the same time, problems such as rising raw material costs, slow cross-border shipping and supply chain bottlenecks have yet to be fundamentally alleviated, and foreign trade enterprises, micro, small and medium-sized enterprises in particular, still face considerable operating pressure. The price of natural graphite operated by foreign trade enterprises will also fluctuate with the changes of the epidemic. Contact us for the latest quotation on natural graphite.
