Carbon furnace <suitable for graphitization and high-temperature modification of carbon materials>
Graphitization / High-temperature annealing / Surface modification / Ash content reduction all in one machine. Compatible with vacuum × Ar/H2, achieving high reproducibility for research to small-scale production heat treatment.
Our company handles "carbon furnaces" that operate at 3000°C and in extremely low oxygen conditions. We address challenges such as the inability to reduce oxygen partial pressure, leading to oxidation and decarbonization in high-temperature regions that prevent achieving target characteristics, as well as the limited tray flexibility and low processing capacity/strict sample size constraints of tube furnaces. These furnaces can be used for applications involving graphite materials, graphite foils, graphite sheets, isotropic graphite, and molded bodies. [Reasons for Effectiveness in Graphitization] - Easy to create extremely low oxygen: The furnace material captures residual oxygen chemically due to its carbon composition, and the vacuum replacement eliminates air inside the sample beforehand. - Temperature range of 3000°C: Stable heat distribution and retention in the -3000°C graphitization zone, with rapid attainment and high reproducibility. - Flexibility in tray/sleeve design: Rectangular sleeves and stacking allow for simultaneous processing of multiple samples, speeding up condition setting. - Atmospheric flexibility: It is possible to combine vacuum/Ar/N2/low concentration H2 to reduce defects and facilitate thermal desorption. *For more details, please feel free to contact us.
