Babbitt metals are one of several alloys used for the bearing surface in a plain bearing. Babbitt metals are characterized by their resistance to galling. The Babbitt metals provide sufficient softness for excellent conformability and embeddability, offering good fluid-forming properties. They are easily cast, can be rigidly bonded to Cast Iron, Steel, or Bronze, run satisfactorily against a Steel shaft, and show excellent corrosion resistance. Babbitting is a process by which softer metals are bonded chemically or mechanically to a shell or stiffener, which supports the weight and torsion of a rotating, oscillating, or sliding shaft. All Babbitt metals are available as Ingot.

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound that is a white crystalline solid and has a unique combination of thermal, electrical, optical, and mechanical properties. Beryllia is an electrical insulator and an excellent thermal conductor, with conductivity higher than any other non-metal except diamond and many metals. It is an ideal material for applications requiring large heat dissipation and dielectric and mechanical strength. Beryllia’s high melting point leads to its use as a refractory material.

Note: Beryllium oxide is toxic; beryllium oxide ceramics are not toxic.

Available purity 99.5%, 99.7%, and 99.98% trace metals basis

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.

Nanorods, or quantum rods, are short nanowires that seem rigid and straight and are one-dimensional structures that provide a directed path for electrical transport. They are shaped like long sticks or dowels with a diameter in the nanoscale but a length that is much longer and aspect ratios between 2 and 50. Their mechanical, electrical, and optical properties depend upon their size, allowing for multiple applications. Also, nanorods may be functionalized for different applications.

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.

Reade offers a variety of single-crystal elements and compounds. These materials have a continuous and consistent crystal lattice throughout the sample with no grain boundaries. Chemical and physical properties will vary depending on the crystal. Numerous shape and size options are available, please specify the size in the comments. Purities are as high as 99.999%, down to low-purity recycled abrasive grains or powders.

Sols are colloidal suspensions of small (<250nm) material particles within a solution and are typically composed of metal oxides. Through various processing steps, colloidal particles within the suspensions can be converted into gel-like networks by removing the solvent from the sol to cause the particles to “bridge” with themselves. Using sols and the sol-gel process, it is possible to fabricate advanced materials in various forms: ultrafine or spherical-shaped powders, thin film coatings, fibers, porous or dense materials, and extremely porous aerogel material.
