Check the specifications of the electric furnace needed for trial production and condition exploration.

Are you selecting electric furnaces for research and development solely based on maximum temperature? In research and development, particularly in material development, there are cases where you want to compare multiple conditions of temperature, time, and atmosphere while the firing conditions are not yet established. Additionally, challenges may arise such as having a small sample size, wanting to use atmospheres like N₂, Ar, H₂, NH₃, O₂, vacuum, or humidified air, and needing to check safety aspects like powder dispersion, gas generation, corrosion, and explosion limits. This document organizes the specifications that should be confirmed when considering electric furnaces for research and development, as well as guidelines for selecting furnace types based on purpose. ■ For selecting electric furnaces in the research and development and material development stages ■ For initial considerations in prototyping, condition exploration, and small-scale firing ■ For considering firing tests in multiple atmospheres ■ For organizing specifications before requesting estimates ■ Can be used as internal discussion material before equipment introduction Even at a stage where conditions are not yet determined, we will propose ways to proceed with firing tests and equipment specifications based on sample shape, temperature range, and atmospheric conditions.
