T/NXCL 023-2023 Determination of hydrogen and nitrogen in Beryllium— Inert gas fusion infrared absorption/ thermal conductivity method (English Version)
Metal beryllium, with its low density, high stiffness, high melting point, and very strong thermal neutron scattering ability, is used as a special functional and structural material in the nuclear field, national defense and aerospace fields. It has an irreplaceable role among current metal materials. Strategic and critical. Hydrogen and nitrogen are harmful non-metallic elements in beryllium, which are mainly brought in by the powdering and pickling process steps. They will have adverse effects on the performance of the product blank, so they need to be strictly monitored. Therefore, accurate detection of hydrogen and nitrogen in beryllium is of great practical significance in promoting beryllium process improvement and product quality assurance. This document specifies the method for determination of hydrogen and nitrogen content in beryllium.
