Selection of furnace for vacuum atmosphere sintering | Supports degassing, oxidation suppression, and high purity processing.

Select the appropriate electric furnace according to the vacuum level and processing purpose.

In vacuum atmosphere sintering, the required pressure and furnace configuration vary depending on the purpose. For degassing and drying, a pressure range of several Pa to several hundred Pa is sufficient, while for oxidation suppression, vacuum pumping and N₂/Ar replacement are necessary, and for high-purity processing, high vacuum levels of 10⁻³ to 10⁻⁴ Pa may be required. Therefore, it is important to consider not only the simple condition of wanting to sinter in a vacuum but also the processing purpose, temperature range, residual O₂, amount of generated gas, materials inside the furnace, heater materials, exhaust system, and safety measures. This document organizes the necessary pressure guidelines, furnace type selection, and confirmation points that affect equipment specifications based on the purposes of vacuum atmosphere sintering. - For considerations of degassing, drying, and oxidation suppression - For considerations of sintering in high vacuum and high-purity atmospheres - For differentiating between metal furnaces, multi-furnaces, carbon furnaces, and tube furnaces - For organizing specifications and considering sintering tests before equipment installation
