Web18 jan. 2024 · As mentioned, bakeout is one of the most commonly used and reliable passivation techniques. From 100–500°C is required to remove water vapour; higher temperatures up to 1000°C are required for hydrogen removal from the material’s bulk. Longer and repeat baking leads to lower outgassing rates, as shown in the graph below.
