Graphene spray guns are a kinetic spray system that deposits, through supersonic acceleration, a one atom thick sheet of pure carbon named graphene by means of a de Laval nozzle, [1] which is a pinched tube with an hourglass type shape. The system deposits graphene flakes and a hexagonal graphene lattice is created upon impact of the desired ...
Aquadag is a trade name for a water-based colloidal graphite coating commonly used in cathode ray tubes (CRTs). It is manufactured by Acheson Industries, a subsidiary of ICI. The name is a shortened form of "Aqueous Deflocculated Acheson Graphite", [1] but has become a generic term for conductive graphite coatings used in vacuum tubes. Other ...
Graphite is characterized by two main groups: natural and synthetic. Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.5−99.9%). Primary grade synthetic graphite can approach the good lubricity of quality natural graphite. Natural graphite is derived from mining.
Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives. The lubricant is applied to a substrate by spray, dip or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases the wear life of the substrate to which it has been applied.

In 2010, GrafTech acquired two companies: Seadrift Coke LP, a manufacturer of petroleum coke, which is an essential component in the production of graphite electrodes; and C/G Electrodes LLC, which manufactures graphite electrodes. [5] In March 2011, the company acquired Micron Research Corporation, a manufacturer of superfine-grained graphite. [6]
A tube of commercial graphite powder lubricant with molybdenum disulfide additive (called "molybdenum") [33] Due to weak van der Waals interactions between the sheets of sulfide atoms, MoS 2 has a low coefficient of friction. MoS 2 in particle sizes in the range of 1–100 μm is a common dry lubricant. [34]
