Reproducibly perform graphitization, carbonization, nitridation, and high-temperature modification in an extremely low oxygen atmosphere.

The "carbon furnace" we handle is an electric furnace designed for high-temperature processing at around 3000°C in an extremely low-oxygen atmosphere. By using vacuum replacement, the air inside the furnace is preemptively expelled, and the getter effect of the carbon material reduces residual oxygen and oxidizing components. It is structured to suppress oxidation, decarburization, and re-oxidation in high-temperature regions, making it easier to reproduce processing conditions such as graphitization, carbonization, nitridation, and high-temperature modification. It can be applied to high-temperature processing of carbon materials, carbon black, CNT, CNF, graphite sheets, ceramics, powder metallurgy materials, semiconductor fixtures, and more. 【Features】 ■ High-temperature sintering in an extremely low-oxygen atmosphere ■ Usable at a constant 2800°C, with a maximum of 3000°C ■ Reduction of residual air in the furnace through vacuum replacement ■ Oxygen getter effect from the carbon material ■ Design allows for simultaneous processing of multiple samples with a saya-tray configuration *For more details, please download the materials or contact us.

basic information

【Available Processing】 ■ Graphitization and high-temperature modification of carbon materials ■ Generation of carbides such as SiC, TiC, ZrC ■ Nitride reaction tests in an N2 atmosphere ■ High-temperature sintering of ceramics and powder metallurgy materials ■ High-temperature reduction, deoxidation, recrystallization, and phase formation evaluation 【For such challenges】 ■ Oxidation and re-oxidation occur during high-temperature processing ■ General furnaces lack temperatures in the range of 2400 to 3000°C ■ Target reactions do not proceed due to residual oxygen in the furnace ■ Tube furnaces lack sample size and tray flexibility ■ Comparison of multiple conditions in the same batch is desired *For more details, please download the materials or contact us.
