What gases can be passed through a rotating inclined tube high-temperature furnace?

The rotating inclined tube high-temperature furnace can be filled with inert or reducing gases such as nitrogen (N ₂), argon (Ar), hydrogen (H ₂), etc. Some equipment also supports oxidizing gases such as oxygen (O ₂) and customized mixed gases. The following is a detailed explanation of its gas communication function:

Inert gases: Nitrogen, argon and other inert gases have stable chemical properties and do not react with materials at high temperatures. They can effectively isolate oxygen and prevent material oxidation. For example, during the annealing process of semiconductor materials, introducing argon gas can prevent the formation of an oxide layer on the surface of the material and ensure its electrical properties.
Reductive gases: Hydrogen and other reducing gases can react with oxides on the surface of materials at high temperatures, reducing them to metals or low valent oxides, thereby improving the purity and performance of materials. For example, in the heat treatment process of metal powder, introducing hydrogen gas can remove oxides on the surface of the powder and improve its sintering activity.
Oxidative gas: Some rotating inclined tube high-temperature furnaces support the introduction of oxidizing gases such as oxygen to meet the specific material’s demand for an oxidizing atmosphere at high temperatures. For example, in the preparation process of ceramic materials, introducing oxygen can promote the oxidation reaction of ceramic materials, form specific crystal structures, and improve the performance of ceramic materials.
Customized mixed gas: According to experimental requirements, the rotating inclined tube high-temperature furnace can also be filled with customized mixed gas to simulate specific reaction conditions. For example, in catalytic reaction research, a mixed gas containing a specific ratio of hydrogen and nitrogen can be introduced to study the activity of the catalyst under different atmospheres.
