General Structure and Properties of Materials (Including Metallographic Methods), be thoroughly outgassed. The process of outgassing is usually accomplished by heating, either prior to or during the pumping process. The rate of gas evolved throughout this process increases with the outgassing temperature. Generally no further gas should be evolved from the parts contained in the

Surface Treatment of Metallic Vacuum Tube Elements, tube. This implies not only the removal of surface impurities, but also the removal of the causes of formation of chemical compounds (e. g. metallic oxides). It is recommended that initially all rough impurities be removed mechanically (sanding, brushing, swabbing). Thin layers of impurities are re

Exhaust Processes of Vacuum Tubes,sorption, contamination of surfaces), as well as economy (life and cost of operation of preliminary outgassing furnaces with high temperature), generally require that parts in sealed off tubes be outgassed again during the pumping process. The limiting temperature permissible in such outgassing is d
