Stable processing of graphitization, carbonization, and ultra-high temperature sintering at extremely low oxygen levels and 3000°C grade.

The "carbon furnace" is a heating furnace designed for ultra-high temperature processing at around 3000°C, constructed with heaters, insulation materials, and furnace walls made of graphite. By maintaining a low oxygen concentration through vacuum replacement and an inert gas atmosphere, it suppresses oxidation and re-oxidation at high temperatures, allowing for processes such as graphitization, carbonization, sintering, crystallization, and high-temperature modification. It is suitable for high-temperature processing of materials that require higher temperatures or specific atmospheres than typical electric furnaces can provide, including carbon materials, C/C composites, SiC, B4C, ceramics, and metal powders. 【Features】 ■ Capable of ultra-high temperature processing at around 3000°C ■ Forms a low-oxygen atmosphere with vacuum replacement and inert gas ■ Applicable for improving graphitization and crystallinity of carbon materials ■ Supports high-temperature sintering of ceramics such as SiC and B4C ■ Compact design makes it easy to introduce for research and development or condition testing *For more details, please download the materials or contact us.
