用χ-射线光电子能谱(XPS)和视线残余气体分析(line of sight residual gas analysis—LOSRGA),对数个非蒸散型吸气剂的激活作了研究。正如人们所知,XPS或ESCA技术,常用来探视表面的化学变化,而LOSRGA技术,常用来确定放出气体的类型和相对数量。所研究的吸气剂。据称是锆的金属粉末与石墨的混合物,内嵌一个(?)绕热供间接加热用。根据制造厂家提供的加热电流对温度的关系曲线,确定吸气剂的激活温度。本文提供的数据记录表明,吸气剂的激活产生一种近金属性的Zr表面。所释放的气体主要是H_2,也释放一些H_2O、CO和CO_2。吸气剂同气体生成稳定的化合物,如ZrO_2、ZrH_2、ZrC等。这可以从XPS谱线的变化观察到。在此之前,吸气剂继续保持活性。
Activation of several non-evaporable getters was investigated using X-ray photoelectron spectroscopy (XPS) and line of sight residual gas analysis (LOSRGA). As is known, XPS or ESCA techniques are commonly used to examine chemical changes in the surface, whereas LOSRGA techniques are commonly used to determine the type and relative amount of gas evolution. The studied getter. Allegedly a mixture of zirconium metal powder and graphite, embedded a (?) Around the heat for indirect heating. According to the heating current supplied by the manufacturer on the temperature curve to determine the getter activation temperature. The data provided in this paper show that the getter activation produces a near-metallic Zr surface. The gas released is mainly H 2 and also releases some H 2 O, CO and CO 2. Getters gas with the formation of stable compounds, such as ZrO_2, ZrH_2, ZrC and so on. This can be observed from the XPS line changes. Until then, getters have remained active.
