High Temperature Vacuum Muffle Furnace

The high-temperature vacuum muffle furnace heats a sealed chamber through electric heating elements and evacuates air to remove oxygen, preventing sample oxidation. It is used for high-temperature processing, sintering, and annealing of materials, and is suitable for heat treatment processes in industries such as ceramics, metals, and glass.
Selection
Select the furnace chamber volume based on the sample size, choose the type of heating element according to the process temperature, match the vacuum level with material requirements, align temperature control accuracy with process needs, determine the cooling rate based on the production cycle, and ensure material compatibility with sample characteristics.
