Promotes the densification of ceramics through gas-type-independent humid atmosphere sintering.

In the ceramics industry, densification is essential for improving the strength and durability of products. Particularly during the firing process in high-temperature environments, atmosphere control significantly affects quality. Instability in humidity control, slow switching of atmospheric gases, and the risks of condensation and contamination are major challenges in the densification process. These challenges can lead to variations in product quality and reduced yield. Our multi-atmosphere furnace is equipped with direct humidity control from Wetter, vacuum replacement, and gas switching functions, addressing these challenges in the ceramics densification process. 【Application Scenarios】 - Ceramics sintering - High-density processing - Surface modification 【Benefits of Implementation】 - Achieving a uniform firing environment - Manufacturing high-quality ceramics products - Improving process reproducibility

basic information

【Features】 - Humidification system independent of gas type: Directly connects to Wetter for setting humidity levels for N2/Ar/air (small amounts of H2 also acceptable). - Vacuum replacement → gas replacement: Pre-removes air from the sample interior, achieving the desired humid atmosphere from the start. - Speed of switching: Easily switch between dry/wet and N2/Ar/air (small amounts of H2). - Stacked × rectangular sheath: Shortens cycle time for parallel testing of multiple samples under the same conditions. 【Our Strengths】 Our company uniquely combines the three technologies of "electricity," "equipment," and "chemistry" to develop innovative heating furnaces and other equipment. We support innovative manufacturing with our customers through advanced heating solutions.

Applications/Examples of results

【Regarding these issues】 ■ We want to stably supply gas derived from cylinders at a specified dew point and sinter it in a humid atmosphere as is. ■ Humidification tends to fluctuate/changes are slow, resulting in a lack of reproducibility. ■ We are hesitant to proceed due to fears of condensation, backflow, contamination, and corrosion. ■ In tube furnaces, the degree of parallelism is low, and it takes time to establish conditions. *For more detailed information, please download the materials or feel free to contact us.
