Metal furnace | High-purity heat treatment furnace free from contamination, such as extreme vacuum and furnace materials.
High-purity heat treatment with reduced contamination from furnace materials using extreme vacuum and metal hot zones.
The "Metal Furnace" we handle is an electric furnace designed for high-purity heat treatment in an ultra-high vacuum atmosphere. By constructing the hot zone inside the furnace with metal materials, we suppress outgassing and carbon contamination from graphite materials, insulation materials, and organic substances, creating an environment that facilitates the evaluation of the material's inherent surface reactions and phase changes. In the metal furnace, clean heat treatment is possible by using metal-based materials for the inner walls, heaters, and fixtures, thereby minimizing contamination from the furnace materials. It is particularly suitable for materials that are sensitive to contamination from furnace materials, those that require accurate evaluation of surface reactions and phase changes, and for annealing precious metals, transition metals, thin films, electrode materials, and optical components. **Features** ■ Compatible with ultra-high vacuum atmosphere - Capable of forming an ultra-high vacuum atmosphere that is difficult to achieve with other electric furnaces - Supports high-purity heat treatment while minimizing the effects of oxygen, moisture, and residual gases ■ Suppression of contamination from furnace materials - Easier to mitigate the effects of furnace material degradation, powdering, and outgassing over long-term use - Applicable to materials that are sensitive to contamination from insulation materials and graphite components Additionally, we can accommodate firing tests using actual samples to confirm conditions before equipment installation. *For more details, please feel free to contact us.*
basic information
【Regarding these issues】 ■ I want to observe the surface reactions and phase changes of the materials I want to evaluate, but the results are disturbed by outgassing from the furnace and the influence of carbon sources. ■ In furnaces using carbon or insulation materials, contamination from the furnace materials due to long-term use is a concern. ■ I want to perform heat treatment in an ultra-high vacuum atmosphere that minimizes the effects of oxygen, moisture, and residual gases. ■ I want to avoid the influence of carbon in the annealing of active solder materials like AgCuTi, ceramics-metal bonding, precious metals, and transition metals. ■ I want to cleanly heat treat materials that emphasize surface conditions and color changes, such as thin films, electrodes, and optical components. 【What can be addressed with a metal furnace】 ■ High-purity heat treatment in an ultra-high vacuum atmosphere. ■ Reduction of outgassing from graphite, organic materials, and insulation materials. ■ Suppression of side reactions and carbon contamination from carbon sources. ■ Reduction of contamination from furnace materials during long-term use. ■ Evaluation of surface reactions, phase changes, color, microstructure, and physical property changes. *For more details, please feel free to contact us.
