What is graphene
Graphene is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of other allotropes of carbon, such as graphite and diamond.
Graphene is an “Advanced material” which at the industrial scale can greatly enhance functionalization from the largest structure to nanoscale electronics.
Graphene incorporation enables stronger, lighter smaller & faster versions of predecessors.
- Inter-facial Shear Strength, thereby reducing shear (sliding) under tension and buckling under compression
- Inter-laminar Shear Strength, allowing for increased surface roughness and wetting ability
- Fracture Toughness
- Crack Propagation
Major Benefits Enabling

Reactor Chamber – perpetuus advanced materials
Vein Graphite (Crystalline graphite)
- Lump graphite (or vein graphite), considered to be one of the rarest, most carbon-rich, and commercially valuable graphite types, occurs in fissure veins or fractures. As massive platy intergrowths of fibrous or acicular crystals, the graphite is understood to be hydrothermal in origin
- Can occur when Carbon settles within a sedimentary horizon
- Derived by metamorphism as carbon precipitates while hydrogen and oxygen are driven off under high pressures and temperature
- Carbon atoms form as sheets or layers resulting in flakes of graphite
- Amorphous graphite: very fine, non-crystalline, structureless graphite, sometimes called
Highly Ordered Pyrolytic Graphite
- Highly ordered pyrolytic graphite refers to graphite that has undergone annealing (recrystallized under heat and pressure) with an angular spread between the graphite sheets of less than 1⁰
Lump Graphite Properties (Gratomic’s Aukam Type)
- Excellent thermal and electrical conductivity
- Perfect Crystallinity
- Chemically inert
- Easy to disperse, mold and blend
- Resistant to oxidation and high temperatures
- Outstanding lubricating properties
- High density
- Environmentally friendly
Graphene: the nano-material of the future
Graphene is emerging as one of the most promising Nano-technology materials because of its unique combination of superb properties. These properties open a way for graphene’s exploitation in a wide range of applications ranging from electronics to optics, sensors, and bio/medical devises.
Electronics is one of the first industries that benefited from graphene’s vast potential. Flexible smartphones, electronic paper, ultra-thin TV sets and a wide range of other devices.
Graphene is an “Advanced Material” with high potential industrial applications. Much like Concrete and Aluminum or Velcro and Gore-Tex. It is a ground-breaking material which has applications in sensor technology. Its single atom thickness would allow for it to finitely detect changes, at the atomic level, within environment which it is introduced. Examples include use in camera sensors or as sensors for the detection of chemicals and gases, including known toxins. Graphene use would allow for the measurement and monitoring of stress and strains within man-made structures such as bridges, and airplanes.
