What gases can be passed through a box type atmosphere furnace?

Box type atmosphere furnaces can be filled with various gases to meet the needs of different materials and processes. Common gases that can be introduced include:
Nitrogen (N ₂):
Nitrogen is an inert gas commonly used to protect materials from oxidation at high temperatures.
Suitable for heat treatment processes of materials such as metals, alloys, ceramics, etc.
Argon (Ar):
Argon is also an inert gas with excellent protective properties.
Commonly used for annealing, quenching, and other heat treatments of materials at high temperatures.
Carbon dioxide (CO ₂):
Carbon dioxide is used as an atmospheric gas in certain specific heat treatment processes.
Its application is relatively limited, but it may have unique roles in the synthesis and modification of certain materials.
Hydrogen (H ₂):
Hydrogen is a reducing gas commonly used in the reduction treatment of certain materials.
During the sintering process of ceramic materials, hydrogen can help remove oxygen impurities from the material.
Oxygen (O ₂):
Oxygen is used in heat treatment processes in certain oxidizing atmospheres.
When preparing certain oxide materials, oxygen needs to be introduced to form the desired oxide structure.
Vacuum:
In addition to the above-mentioned gases, the box type atmosphere furnace can also perform heat treatment under vacuum conditions.
Vacuum conditions help to remove gas impurities from materials, improve their purity and performance.
In addition, according to specific process requirements and material characteristics, the box type atmosphere furnace can also be filled with other specific atmosphere gases, such as trace amounts of hydrogen gas, mixed gases, etc. When choosing an atmosphere gas, factors such as material properties, heat treatment process requirements, and the safety and economy of the atmosphere gas need to be considered.

It should be noted that there may be certain differences in atmosphere control among different models and specifications of box type atmosphere furnaces. Therefore, when using a box type atmosphere furnace for heat treatment, it is necessary to carefully read the equipment manual and operate and maintain according to the equipment requirements.
