Carbon furnace <Excellent reproduction with ultra-low oxygen × 3000°C class × vacuum replacement>
From preprocessing to final firing in one machine. Suitable for research and small-scale production temperature recipes.
Our "Carbon Furnace" allows for the precise reproduction of high-temperature phase transitions, crystallization, and sintering under conditions of "ultra-low oxygen × 3000℃ class × vacuum replacement." It can be used in processes such as promoting phase transitions and recrystallization, controlling grain growth (phase stabilization at high temperatures), densification sintering of ceramics and difficult-to-sinter materials, and energy control of surfaces and interfaces (surface stabilization under low oxygen conditions). It is suitable for developing temperature recipes from research to small-scale production. 【Reasons Why Our Carbon Furnace is Effective (Partial)】 ■ Creates ultra-low oxygen partial pressure - Vacuum pumping → Ar/N2 replacement (dilute H2 if necessary*) to gradually lower the oxygen potential * H2 is operated within the safety design range of the equipment (e.g., below 4%) - The carbon material in the furnace absorbs residual O2 through getter action, suppressing side reactions. ■ High-temperature stability at 3000℃ - Regular use up to 2800℃ / maximum up to 3000℃, with gradual heating and holding for precise control of phase transitions, crystallization, and sintering. *For more details, please feel free to contact us.
basic information
【Reasons Why Our Carbon Furnaces Are Effective】 ■ Parallel Evaluation of Multiple Samples - High tray flexibility with rectangular trays/multi-layer shelves allows for rapid parallel testing under the same conditions. ■ Continuous Process from Pre-treatment to Final Firing - Continuous sequencing of vacuum, replacement, and heating suppresses recontamination and reoxidation. *For more details, please feel free to contact us.

Applications/Examples of results
【Regarding such issues】 ■ The presence of trace amounts of O2 leads to oxidation and decarburization at high temperatures, resulting in unstable phase purity and grain boundary characteristics. ■ It is difficult to achieve consistent temperature application/reproduction, and results vary due to differences in size and fixtures. ■ Recontamination and reoxidation occur as the pre-treatment and main firing are conducted in separate furnaces. ■ The processing capacity in tube furnaces is low. *For more details, please feel free to contact us.
