High Temperature Inert Atmosphere Furnace up to 1700°C

This controlled inert atmosphere heat treatment furnace is pre-vacuumed to ensure that the oxygen content in the furnace is minimized, and then nitrogen, argon is introduced to obtain the desired heating treatment under the protection of the atmosphere. Due to its excellent atmosphere and compactness, it has been widely used in material laboratories or small batch production of semiconductors, silicon nitride, and other products.
