Natural & Synthetic Graphite Powder

Magnesium (Mg) is a light, moderately hard, silvery-white metal that ignites easily in the air and burns with a bright light. It is strong, has good heat dissipation and dampening, and is easy to weld, forge, cast or machine. It can improve the mechanical, fabrication, and welding characteristics when used as an alloying agent since it has a low density and is the lightest structural metal (a third lighter than aluminum). It also has good electrical properties. Magnesium turnings and chips are produced by milling commercial and high-purity magnesium, keeping size under control to obtain the desired specific surface and reactivity. They are silver-white. initially, but can turn to a dark gray if stored improperly. Purity: Standard purity (99.8% Mg) Ultra-high purity (99.98% Mg)

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.

Sponge iron, or direct reduced iron (DRI), is a highly porous, irregularly shaped sponge-like form of iron. It typically has lower bulk density and higher surface area than conventional powders (atomized or carbonyl). It is of high consistency and purity and has high green strength and low growth. Our sponge iron powders have fairly low carbon content (<1%) and typically >97% purity or higher.

Iron metal is a silvery-white, soft metal that encompasses any iron-based powder. It includes carbonyl iron powder and atomized iron powder. Sponge iron can be found here sponge iron powder. Reade offers a range of iron powders including a food grade suitable for iron enrichment.

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.

Hemp Fiber (Bast Fiber) is a high-yield commercial fiber crop that grows from seed. Hemp stalks are harvested for their fibers and grow on the outside of the plant’s stalk, similar to the bark of a tree. Hemp fibers are advantageous as they are flexible, have low density and abrasiveness, and have mechanical properties comparable to glass fiber. There is also quantitative and qualitative homogeneity from one harvest to the next. Degummed Hemp Fiber is processed to remove lignin and pectin, so separated fibers are finer, softer, and more absorbent. Size ranges from ½ inch to 5 inches. Hemp Hurd is derived from the core of the hemp stalks and is also referred to as hemp shives. It looks similar to wood chips. It is porous and absorbent and naturally resistant to mold and bacteria. Raw Long Hemp Fiber is right from the stalk, non-processed, and uncombed with slight separation of fibers. Fibers range from 24 to 72 inches. Combed Hemp Fiber, also known as plumber's hemp, is untwisted and combed. Fiber length ranges from 4-5 inches long.

Boron carbide, or "black diamond", is an extremely hard ceramic material that is a black crystal with a metallic luster. It has physical properties, including hardness, that rank only second to diamond. It is a high-performance abrasive material that is chemically resistant. It has a melting point of 2350ºC high thermal neutron capture capability, is wear-resisting, and has semiconducting properties.

Talc, or Hydrous Magnesium Silicate (3MgO.4SIO₂.H₂O), is a very fine, translucent to opaque, soft mineral with a white to grayish-white color. It is inert, odorless, and insoluble in water. Powder granulations available between 37 microns to 1.5 microns

Electrolytic iron is the purest form of iron, whereby commercial iron has all impurities removed through electrolysis. This electrochemical refining process helps to ensure uniform chemical composition and tight particle size distributions. Cathode deposit is supplied as small, smooth, irregularly shaped iron pieces. Chip from bright annealed and polished high-purity electrolytic iron chips, nominally 3/32” x 3/32” (2.5 x 2.5 mm) approximately 1/64” (400 μm) thick. The chips grade is known for its extremely low sulfur and carbon content and smooth polished uniform chips, which are easy to measure and disperse. Powder grade is available as annealed, unannealed in three different mesh sizes, or kosher certified. Purity 97%+
