Carbon furnace | Supports carbonization reaction tests in low oxygen and high temperature environments.
Pre-evaluation of carbide reactions such as SiC, TiC, and ZrC in low oxygen and high temperature environments.
We can accommodate carbonization and high-temperature sintering tests before equipment installation. Even at a stage where temperature, atmosphere, and processing time are not yet determined, you can consult us regarding the consideration of test conditions based on your objectives. Through preliminary evaluations using actual samples, we can confirm reactivity and utilize this information for equipment specifications. Our company offers a small "carbon furnace" that can be gradually replaced from vacuum to inert gas. It can be used for experiments and processes involving solid-phase carbonization (powder mixing method, coating method, carburizing) and composite carbonization (such as using B4C) to enhance hardness and optimize carbon supply conditions (types, ratios, and contact states of carbon materials). Please feel free to contact us if you have any requests. [Reasons why our carbon furnace is chosen (partial)] ■ Rapidly reaches high-temperature ranges - Stable attainment and maintenance of 1600-2800℃ - Temperature guidelines effective for carbonization: SiC 1600–2000℃, TiC 1500–2100℃, ZrC 1800–2300℃ ■ Suppresses side reactions at extremely low oxygen partial pressures - Vacuum draw → Replacement with Ar/N2 - Reduces residual oxygen through carbon getter materials, suppressing CO generation *For more details, please feel free to contact us.

Applications/Examples of results
【Regarding such issues】 ■ Composition fluctuates due to CO/CO2 side reactions and SiO volatilization ■ Reactions are unstable depending on the type, particle size, and contact state of carbon materials ■ It is difficult to control the temperature, making it hard to balance particle growth and phase purity ■ Due to differences in fixtures and contact, results are difficult to reproduce even under the same conditions 【Examples of test applications before equipment installation】 ■ Confirmation of reactivity of new carbide materials ■ Screening of carbonization conditions for SiC, TiC, ZrC, etc. ■ Comparison of types, particle sizes, mixing ratios, and contact states of carbon sources ■ Small-scale prototyping before mass production furnace installation ■ Basic evaluation with powders, pellets, and small piece samples ■ Comparison of phase formation, particle growth, hardness, color tone, and residual carbon after carbonization *For more details, please feel free to contact us.
