  • Basic Information on Graphite
    be synthesized. It has been known since ancient times and is mined in various regions of the world. Only through purification and refinement does graphite become a high-tech material. Synthetic graphites can be produced by various methods and from various basic substances.
  • EDM - The Graphite Grade Factor - 10/06
    place throughout every step of production. This begins in the selection of raw materials. Different sources for coal tar pitch and coke materials result in different final properties for the graphite that is produced. These raw materials are crushed and sieved numerous times to ensure
  • EDM - Sometimes Graphite Just Isn't Enough - 03/07
    work metals, such as tool steels, are easy to EDM with traditional graphite electrodes. Others are not. Because of their unique characteristics, questions continue to arise about effectively EDMing materials like Beryllium Copper, Titanium and Tungsten Carbide. Even though graph-ite electrodes do
  • High pH Chemical Aging of Asbury 3393 Expandable Flake Graphite
    The purpose of this article is to describe the effects of boiling alkali solution (sodium hydroxide) on the expansion characteristics of 3393 expandable flake graphite. Any change in the expansion ratio of material treated by the method outlined below may indicate changes which could occur
  • Active Brazing Joins Titanium-Graphite Beam Target for Subatomic Particle Detection
    Active metal brazing allows. metals to be bonded directly to nonmetallic. materials without the. need for a metallization. Using an innovative active brazing process to join titanium to graphite,. engineers built a beam target for use in. a ground breaking physics experiment, which. sends subatomic
  • Melting Silicon in Graphite Crucible for Material Testing (.pdf)
    A four turn helical coil is used to heat the crucible. The crucible is wrapped with a layer of insulation and placed into the coil.
  • Heat Aging of 3393 Expandable Graphite
    This technical article describes the effect of heat aging on the overall expansion ratio of expandable, which directly influences the fire retardation capacity of the intumescent material.
  • TruMac CN: Carbon/Nitrogen in Coal, Coke, Carbon, Black & Graphite
    Samples must be of uniform consistency to produce. suitable results, preferably minus 60 mesh. Carbon and. nitrogen results for coal, coke and select reference. materials are typically reported on a dry basis. Therefore,. either the materials must be dried prior to analysis or the. moisture content
