Serialized Part 2: Background of the Development of Small Carbon Furnaces
Introducing the challenges in the research field, directions for solutions, and concepts!
While the demand for dry reduction heat treatment is increasing, the following challenges are prominent in the field. ■ Challenges in Research Settings - Limitations on maximum achievable temperature (recipe design is constrained by material and structural upper limits in tubular furnaces) - Limitations on sample preparation quantity (effective heating area is narrow, making it unsuitable for scale-up considerations) - Difficulty in maintaining extremely low oxygen levels (ppm to ppb level) (due to leaks, residual O2, and fine cracks from heat shock, etc.) ■ Directions for Solutions (Required Specifications) - Uniform heating in a short time: rapid temperature rise, high temperature uniformity, and good response - Flexible scaling: continuous support from small sample sizes to small-scale mass production - Atmosphere control: stabilization of extremely low oxygen levels with Ar/N2 (and a small amount of H2 as needed) plus low residual O2 design ■ Concept Graphite heating element × high insulation structure × low leak design. A compact carbon furnace optimized for prototyping and condition setting, enabling faster and more reproducible dry reduction processes. *For more details, please download the PDF or feel free to contact us.
