Introduction to the applications of small carbon furnaces, such as graphitization, carbonization, sintering, and high-temperature reaction evaluation.

Our "Small Carbon Furnace" is an electric furnace designed for high-temperature processing at around 3000°C in a low-oxygen atmosphere. By using graphite components inside the furnace and treating it in an inert gas atmosphere such as Ar or N2 after vacuum replacement, we create a stable heating environment that suppresses oxidation and re-oxidation at high temperatures. This document introduces the main applications of the small carbon furnace, including the synthesis and sintering of high-temperature materials, high crystallization of carbon materials, high-temperature processing and reduction reactions of metal materials, high-temperature gas reaction evaluations, and small-scale testing for research and development. 【Main Application Examples】 ■ Synthesis and sintering of high-temperature materials ■ Graphitization and high crystallization treatment of carbon materials ■ High-temperature processing and reduction reactions of metal materials ■ High-temperature gas reaction evaluations using N2, H2, Ar, etc. ■ Material process evaluations at research and development or prototype scales *For more details, please download the document or contact us.
