Organize the types of furnaces suitable for oxidation, degreasing, and pyrolysis, along with exhaust measures.

Are you considering evaluating oxidation firing, debinding, and thermal decomposition in an O₂・Air atmosphere? For processing in an O₂・Air atmosphere, we focus on using tube furnaces for confirming the reaction behavior of small samples, while multi-atmosphere furnaces are primarily used for evaluating a variety of samples such as powders, substrates, and components with significant debinding amounts. In particular, for debinding and thermal decomposition, it is important to consider the generation of organic components, CO/CO₂, moisture, odors, and dust, and to include specifications that cover not only the furnace body but also the exhaust line, safety measures, and treatment of generated gases. This document organizes the differentiation between tube furnaces and multi-atmosphere furnaces for O₂・Air atmosphere firing, items to be confirmed in advance, and considerations for exhaust and safety measures. ■ For selecting furnace types for oxidation firing, debinding, and thermal decomposition evaluation ■ For confirming the differentiation between tube furnaces and multi-atmosphere furnaces ■ For confirming the reaction behavior of small samples ■ For evaluating the debinding of powders, substrates, and components ■ For firing tests and condition exploration before equipment installation

basic information

Publication Content: Points for Selecting Furnaces for O₂ and Air Atmosphere Sintering ■ Tubular Furnace: Small Quantity, Gas Flow, Reaction Behavior Confirmation Suitable for oxidation and thermal decomposition evaluation with small samples, confirming reactions under O₂/Air flow, comparative tests with boats and small crucibles, and condition exploration in short cycles. Key confirmation items include reaction tube size, boat material, gas flow rate, and exhaust line. ■ Multi-Atmosphere Furnace: Powder, Substrate, Component, and Degreasing Evaluation Suitable for cases where sample shapes are diverse, such as powders, substrates, and components, or when the amount of degreasing and generated gas is relatively large, including considerations of furnace volume and exhaust system. Key confirmation items include sample quantity, jig configuration, exhaust volume, and safety measures. Five Items to Confirm in Advance for O₂ and Air Atmosphere Sintering ■ Purpose: Oxidation, Degreasing, Thermal Decomposition ■ Sample: Powder, Substrate, Component, Jig ■ Atmosphere: Air or O₂ Concentration Control ■ Exhaust and Safety: Generated Gas, Dust, Odor ■ Evaluation and Design: Reflecting Results in Equipment Specifications

Applications/Examples of results

This is recommended for such considerations. ■ Oxidation firing in O₂ and air atmosphere ■ Evaluation of the degreasing of organic components and binders ■ Confirmation of pyrolysis behavior, generated gases, and weight changes ■ Gas flow tests and reaction behavior confirmation for small samples ■ Evaluation of oxidation, degreasing, and pyrolysis for powders, substrates, components, and jigs ■ Comparison of air atmosphere and O₂ concentration control conditions ■ Consideration of exhaust and safety measures assuming CO/CO₂, moisture, odors, and dust ■ Condition exploration before equipment installation, firing tests in a small furnace ■ Consideration of furnace volume, exhaust system, jigs, and safety specifications based on test results We are available for consultations from the early stages of consideration, such as "Is a tubular furnace sufficient for small-scale evaluations?" and "Which furnace configuration is best if there is a large amount of degreasing?"
