Although classified as a non-metal, graphite demonstrates properties similar to metals. It conducts heat and electricity efficiently, offers high strength and rigidity, and maintains its structure even at very high temperatures above 3,600°C. It is also chemically stable, lightweight, and naturally lubricative, which enhances its usefulness across various industries.
Why is Graphite Testing important?
Graphite testing evaluates the purity, structure, and physical properties of natural or synthetic graphite, including particle size, ash content, density, and conductivity, to verify material quality for industrial applications such as batteries,refractory materials, lubricants and nuclear uses.

FAQ
Graphite testing involves analytical methods, along with techniques like XRF and thermal testing to assess its composition, purity, and key characteristics.
Graphite is known for its strong electrical and thermal conductivity, layered structure that enables lubrication, and high carbon purity.
Pure graphene is a single layer of carbon atoms arranged in a hexagonal lattice, making it 100% carbon.
At standard room temperature and pressure, it is one of the most stable forms of solid carbon. It has a very high melting point (around 3,600°C), meaning it stays solid even under extreme heat. Interestingly, graphite doesn’t typically turn into a liquid when heated at normal atmospheric pressure; instead, it sublimes, turning directly from a solid into a gas.
Common parameters include fixed carbon, ash content, moisture, sulfur, and elemental composition.
Ash content is a direct indicator of purity; the lower the ash content, the higher the carbon purity and quality of the graphite.
It helps detect impurities, maintain consistency, and ensure the material meets required specifications for industrial use.
