Pyrolytic graphite is pyrolytic carbon with high crystalline orientation deposited by chemical vapor phase deposition on a graphite substrate at 1800°C to 2000°C under a certain furnace pressure of high-purity hydrocarbon gas. It has a high density (2.20g/cm ), high purity (impurity content 0.0002%) and anisotropy in thermal, electrical, magnetic and mechanical properties. It can still maintain a vacuum of 10mmHg at around 1800°C.
Pyrolytic graphite application examples:
1. The heating rate of PG/PBN heater is extremely fast, and the outgassing rate is extremely low. This heating material is an ideal heating material for semiconductor industries and applications that require high vacuum, high temperature and high purity. For example: semiconductor substrate heating (MBE, MOCVD, PVD, CVD, etc.), superconductor substrate heating, rapid annealing furnace, electron microscope sample heating, metal evaporation heat source, gas heating nozzle heater, etc.
2. Pyrolytic graphite has outstanding characteristics such as low density, high temperature, high strength, good ablation resistance, and excellent thermal shock resistance. It is an ideal throat lining material for tactical missile engines.
3. Pyrolytic graphite is a very common ion beam grid preparation material, which has the characteristics of high purity, low corrosion rate and limited thermal expansion. The role of the ion beam grid is to extract the ions in the discharge chamber plasma through a series of electrostatic grids with many small holes in a precise arrangement.
4. PG crucible has the advantages of high purity, compactness, low air permeability (same as glass), high temperature resistance, acid and alkali corrosion resistance, resistance to sudden cooling and sudden heat changes, and easy washing. PG crucibles are superior to platinum, silver, nickel and other crucibles in some respects.
Main market applications:
L.T Group has a comprehensive product and technology portfolio that focuses on four field of graphite - ultrafine particle graphite mould,graphite electrode, graphite crucible, as well as other products mainly made of graphite.
Graphite materials exhibit unique properties such as good electrical and thermal conductivity, heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.
