FAQ
Focus on answering common questions to provide users with clear and practical usage guidelines:
-
Q:What are the roles of different atmosphere gases during sintering?
A:Argon: Highly inert and dense, it's suitable for high-temperature sintering of easily oxidized materials. It effectively isolates oxygen and doesn't react with the material.Nitrogen: Low-cost and suitable for materials insensitive to nitrogen. In some cases, it can serve as both a shielding gas and a reactant. Hydrogen: A reducing gas, it's used for materials requiring surface oxide removal. It can reduce metal oxides, but its flammability and explosiveness should be considered.
-
Q:Is there a strict order for vacuuming and introducing atmosphere?
A:The order of "vacuuming first, then introducing atmosphere" must be followed. The reason is that if the atmosphere is introduced before vacuuming, the air in the furnace will mix with the atmosphere gas, making it impossible to completely eliminate oxygen.
-
Q:What are the consequences of reversing the order?
A:Furthermore, gas compression may cause pressure fluctuations in the pipeline, shortening the life of the vacuum atmosphere sintering equipment.
