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

The box type vacuum atmosphere muffle furnace can pass various gases, mainly including the following categories:

1. Inert gases: such as nitrogen, argon, etc. These gases have stable chemical properties and are not easily reactive with materials. They can effectively isolate oxygen and prevent materials from oxidizing at high temperatures. They are suitable for processing materials that are sensitive to oxidation, such as metal powders, lithium battery materials, semiconductor materials, etc.
2. Reductive gases: such as hydrogen gas. Hydrogen has certain reducibility at high temperatures and can be used for material reduction treatment, such as removing oxides on the surface of metal materials during heat treatment, improving the purity and performance of materials.
3. Other gases: According to specific process requirements, gases such as oxygen, carbon monoxide, and ammonia decomposition gas can also be introduced. For example, in certain special chemical reactions or material synthesis processes, a specific gas environment is required to achieve the expected reaction effect.
