Carbon Based Materials

Activated carbon, also called activated charcoal, is highly porous, contributing to its very large surface area. Its surface is also very reactive. It is a very useful adsorbent used in many filter systems to purify, dechlorinate, deodorize, and decolorize both liquid and vapor applications. Activated carbon is usually derived from waste products such as coconut or wood, where bulk sources are converted into charcoal before being 'activated.' Activated carbon from coal is referred to as activated coal. Activated carbons are economical adsorbents for many industries and purposes. Different types of activated carbon are suited for various specialized applications, with grade and size-specific applications.

Amorphous carbons include Carbon Black, Furnace Black, and Channel Black. They are black pigments produced by the thermal decomposition of natural hydrocarbons. These are free and reactive carbons with no crystalline structure. Reade offers furnace black. Nominal purity= 98.5 to 99.6% Available in bead, ground, and powder form with particle sizes ranging from 16 to 280 nanometers.

Buckypaper is a macroscopic aggregate of thin sheets of aggregated carbon nanotubes. It is one-tenth the weight of steel, but up to 500 times stronger, with the ability to conduct electricity and disperse heat. Buckypaper has low optical reflectivity and thermal conductivity.

Carbon is a pure non-metallic element found only in the forms of diamonds and graphite. Graphite is widely used for many applications because of its unique combination of properties. It is slippery to the touch, a good conductor of electricity and heat, is chemically inert, and can withstand high temperatures and corrosive environments. 99% to 99.99% (metals basis)

Carbon nanotubes (CNT) are tubes made of carbon atoms with nanometer diameters. Reade supplies a variety of carbon nanotubes. While many specific properties of CNTs are type dependent, in general, carbon nanotubes have high electrical conductivity. They have good thermal conductivity along the tube axis that is comparable to diamonds while exhibiting elastic, flexible, stiff, tough, and strong fibers while maintaining the chemistry of carbon molecules and being free of molecular defects. This carbon chemistry allows strong Van der Waals attraction which leads to spontaneous self-assembly and roping of many nanotubes, which may be important in certain applications. Single-wall carbon nanotubes (SWNT) are an intermediary allotrope of carbon between fullerene cages and flat graphene. Double-wall carbon nanotubes (DWNT) are similar to SWNT but are more resistant to chemical attacks. Multi-wall carbon nanotubes consist of multiple rolled layers of graphene. Dry powder form and dispersions available.

Diamond Dust is composed of pure carbon. Diamond powder is a super-abrasive and is offered in two categories: synthetically grown and naturally grown. Naturally mined diamond purity is 99+%. Synthetic diamond purity is 99%.

Graphene Nanoplatelets are nanoparticles made from graphite that can substitute carbon fiber, carbon nanotubes, nano-clays, or other compounds in many composite applications. These nanoparticles consist of small stacks of graphene (3-10 nanometers) that are safer than carbon nano-fibers and nano-tubes and improve reliability, thermal conductivity, and electrical conductivity while reducing porosity when added to plastics or resins. Graphene Nanoplatelets help products built on them exhibit improved tribology, mechanical, biomedical, gas barrier, flame retardant, and heat convection properties. They can be used with other additives to enhance cost and material efficiency.

Graphene oxide, also known as graphite oxide, is a compound of carbon, oxygen, and hydrogen in variable ratios that is obtained by treating graphite with strong oxidizers. Graphene oxide has many unique properties, including a two-dimensional planar structure, large surface area, chemical and mechanical stability, superb conductivity, and good biocompatibility. It is an insulator and can almost be considered a semiconductor. Purity: 97% - 99% Graphene Oxide Safety Notice: Before using, the user shall determine the product's suitability for its intended use, and the user assumes all risk and liability whatsoever in addition to that.

Graphite is a soft dark grey solid of crystallized carbon. Graphite is a good conductor of heat and electricity, and due to the atomic arrangement into easily cleaved layers, graphite is used as a solid lubricant. It is odorless, tasteless, non-toxic, and chemically inert to acids and alkalis under most conditions. Many different standard granulations are available between 5 mesh USS and 0.7 microns

Single crystal diamond is a manufactured product for industrial applications and produced by a high pressure/high temperature (HPHT) synthesis process and tightly controlled crystal growth conditions. Repeatable physical characteristics and dimensional consistency are the notable features of a synthetic single-crystal diamond. Diamond excels in its electronic properties and has high thermal conductivity and chemical stability.
