Some cold plates used in cooling specialty electronics are being designed using composites such as Al-SiC or Al-Gr, graphitic foams, pyrolytic graphite, and composites that contain diamond to manage thermal coefficients of expansion. In some electronic package applications, ceramics such as silicon carbide and aluminum nitride are also being used. Graphite Bonding, Carbon, Carbide Joining Techniques » S Joints are made at lower soldering temperatures and can be reworked. SB joining mitigates thermal expansion mismatch issues experienced in brazing. S-Bond® alloys include:S-Bond 115 & 130, which join from 115 to 130°C with Sn-In base. S-Bond 140, which joins at 140°C with Bi-Sb base. S-Bond 220, which joins from 250-270°C., with Sn-Ag base.
Synthetic graphite was discovered accidentally in the late 1800s. This high purity, highly crystalline material is used in a variety of applications including friction, foundry, electrical carbons, fuel cell bi-polar plates, coatings, electrolytic processes, corrosion products, conductive fillers, rubbers and plastic compounds, and drilling applications.

The floater magnet is then repelled equally by the two graphite plates and becomes suspended in mid-air. See our recent article about the magnet levitator here . The kit includes the levitation jig shown above complete with pyrolytic graphite as the diamagnetic material, nine neodymium magnets to experiment with, and a detailed instruction sheet.
