The oxygen concentration can be reduced to the limit, preventing oxidation! By improving the crystallinity of carbon materials, lifespan and performance are significantly enhanced.
The "carbon furnace" is a high-temperature heating furnace composed entirely of graphite (carbon) for the heater, insulation, and furnace walls. It enables heating in the high-temperature range of around 3000°C, which is difficult to achieve with conventional electric furnaces, while also keeping the oxygen concentration inside the furnace to an extremely low level. It is suitable for processes that require high temperatures and low oxygen, such as the sintering of carbon materials that need high crystallization and ultra-high melting point metals. 【Features】 ■ Ultra-high temperature compatibility ■ Low oxygen atmosphere ■ Suitable for high crystallization processing ■ Wide range of material compatibility *For more details, please download the PDF or feel free to contact us.

basic information
**Principle** - Heating method: Direct heating by passing current through a graphite heater, raising the temperature of the entire furnace through radiant and conductive heat. - Atmosphere control: To prevent oxidation reactions at high temperatures, the operation is conducted in an inert gas atmosphere such as Ar or N2, reducing the oxygen concentration to the lowest possible level. - High-temperature compatible structure: All components inside the furnace are made of high-purity graphite, achieving stable heating up to 3000°C. *For more details, please download the PDF or feel free to contact us.*
