T/NXCL 023-2023 Determination of hydrogen and nitrogen content in beryllium using inert gas fusion-infrared absorption/thermal conductivity method
Basic Information
Scope
Main technical content: Metal beryllium, with its low density, high rigidity, high melting point, and very strong thermal neutron scattering capability, is used as a special functional and structural material in the nuclear field, national defense, and aerospace aviation fields. It plays an irreplaceable strategic and critical role in current metal materials. Hydrogen and nitrogen are harmful non-metallic elements in beryllium, mainly introduced by powder-making and acid-washing process steps, which can adversely affect the performance of the product blank. Therefore, strict monitoring is necessary. Therefore, accurate detection of hydrogen and nitrogen in beryllium is of great practical significance for promoting the improvement of beryllium processing technology and ensuring product quality. This document specifies the method for determining the hydrogen and nitrogen content in beryllium.
