What is ​crystal vein graphite?

In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco, 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 crystal vein graphite will also be affected to a certain extent.

Crystal vein graphite is also known as crystal vein, Sri Lankan graphite, Ceylon graphite and graphite. The names Sri Lanka and Ceylon are derived from the areas where this graphite is mined. It is only sourced and processed in Sri Lanka (formerly Ceylon), although this form of natural graphite is also found in the UK and USA.

The exact formation of crystalline vein graphite is uncertain, but it is suspected that the graphite is naturally occurring pyrolytic graphite. If it was deposited directly from the fluid phase, as this theory suggests, that would explain the graphite veins found in the ore rocks.

In layman's terms, a high temperature fluid may deposit solid graphitic carbon as it flows. Once the fluid cooled, this graphitic carbon formed graphite flows or veins in the surrounding rock. Carbon rich gases may react with the high temperature fluid to form deposited graphitic solids, or they may be absorbed as the fluid flows.

This formation helps to create a macroscopic form, like a small needle perpendicular to the wall of a vein. Such veins of natural graphite can be from a few centimetres thick to 2 metres thick. When sourced, the graphite ranges in size from powders as fine as 5 microns to lumps as large as 8 cm in diameter.

How does vein graphite compare to other natural graphites?

In many ways, vein graphite is the best quality natural graphite. Its graphite content can range from 94% to 99%, with the purest samples coming from the middle of the vein. It also has a higher thermal and electrical conductivity and a higher cohesive integrity than other types of natural graphite. These properties may be attributed to its needle-like structure.

What are the good uses of crystalline vein graphite?

Veined graphite can potentially be used in any situation where natural flake graphite would be suitable, but the properties of veined graphite would be slightly better. It is commonly used in automotive applications such as high performance clutches and brakes.

Vein graphite is unique in that it is considered to be a naturally occurring pyrolytic (deposited from a fluid phase) graphite. Vein graphite gets its name from the fact that it is found in veins and fractures in closed 'ore' rocks. This graphite is formed by the direct deposition of solid graphitic carbon by high temperature subsurface fluids called pegmatite fluids. Pegmatites form regionally or locally when large amounts of magma cool, or when some other source of 'geological energy' causes the surrounding rock to melt. Fluids from these sources are hot and aggressive at high pressures and may actually be in a state known as 'supercritical', a sub-stable fluid state that is neither liquid nor gaseous. Pegmatites represent substances distilled from heated rock because of their low solubility in the local system. If this fluid intrudes into pre-existing flake graphite deposits or other carbon-bearing rocks, the solid carbon present may be bound to the fluid as carbon dioxide, methane, carbon monoxide or other carbon-bearing fluid phases. Carbonaceous gases may also be formed by the reaction of carbonate mineral species with magma or other energy sources. If limestone, marble or other carbonate-rich mineral species are involved, significant amounts of carbonaceous gas may be formed as a result of the release of 'crystalline carbon dioxide.
