Heat and Wear-Resistant Materials
Carbon composites are routinely used in airplane brakes where light weight, low wear rate, and temperature resistance are critical. Carbon composites also provide self-lubricating features that promote extended life. For example, a specialized brake pack for the V-22 Osprey aircraft was developed in cooperation with Parker Hannifin using a carbon composite coated with silicon carbide This brake surface offers exceptional friction performance over a wide temperature range and excellent wear results.
Ion Grids
PYROID® pyrolytic graphite has an exceptionally low erosion rate (slower than any other material) when subjected to ion bombardment. This compound - with its assay of 99.999% purity, high conductivity and thermal stability - makes it ideal for fabricating low erosion, long life ion grids used in high-power density-plasma cleaning/etching devices and ion implantation equipment.
The aerospace community and NASA engineers see the future of satellite and deep space propulsion as one based on the ion. Ion propulsion offers the satellite industry much higher exhaust velocities that are needed to make satellite launch, station keeping and deep-space missions more affordable. Some 60-70% more mass is required in existing chemical propulsion systems over ion propulsion is used for fuel and oxidizers. The industry is aggressively pursuing alternative propulsion technology to counter the deficiencies of conventional chemical propulsion.
Recent research results indicate PYROID® pyrolytic graphite demonstrated erosion rate at least a factor of three less than molybdenum.
Deposited Shapes
PYROID® pyrolytic graphite is available as custom free standing as deposited shapes, having diameters up to 18 in. (46 cm) and wall thickness of 0.050 in. (0.127 cm). Some of the shapes we manufacture are cylindrical tubes, spherical domes, rods, crucibles, trays, and shapes to match your specifications and drawings.
Glass
Our PYROID® pyrolytic graphite is used as a glass-friendly thermal management material. Continuously Nucleated (CN) Pyrolytic Graphite is most commonly used to make dies and forming tools that shape semi-molten glass. Stemware, container glass, and specialty glass manufactures have found better results when forming glass with PG then traditional graphite. Because of its resistance to thermal shock, it is also used for support pads to isolate annealed glass, preventing localized cooling, which minimizes checking due to thermal stress. PG does not shed particles into, or mar the surface of hot glass, making it an ideal material for glass benders and tempering operations.
PYROID® pyrolytic graphite is oxidation resistant to 650° C (1200° F) and is chemically inert to most glass materials. It is used to shape semi-molten pieces in direct exposure to a reducing gas flame.
PG is easily machined with standard carbide tooling. And PYROID® powder offers superior thermal transfer and added resistance to oxidation.

Analytical Instrument Accessories
Low metallic impurities (< 5 ppm total metallic ash) make Pyrolytic Graphite ideal material for manufacturing atomic absorption spectrograph planchettes, crucibles for plasma vaporization, and sputter-coating scanning electron microscope samples requiring a conductive, non-metallic coating and bio-compatible material requirement.
Rocket Nozzles
PYROID® pyrolytic graphite supplied by the Minteq Pyrogenics Group is used as a throat insert in the U.S. Navy's HARM rocket motor. The unique material properties offer directional conductivity, high temperature strength at 6000° F (3300 ° C) and low weight combine to make this a perfect material for rocket nozzle and other high temperature applications.
Sputtering Targets
The ultrahigh purity (< 5 ppm ash) and high density (2.2 g/cc) of PG material results in sputtered carbon films showing enhanced mechanical and tribochemical wear critical to the protection of rigid disks.
