Determination of Carbon in High Beryllium Beryllium-Alminium Alloy by High Frequency Induction Combustion- Infrared Absorption Spectrometry

The content of carbon in high beryllium beryllium-alminium alloy (w_Be, 60%-65%) directly influenced on the mechanical properties of alloy, so the research as shown in the title was studied. 0.10-0.20 g of the high beryllium beryllium-alminium alloy sample was placed into a ceramic crucible prefilled with 0.3 g of iron flux, and then covered with 2.0 g tungsten-tin flux. Carbon in the sample was determined by high frequency induction combustion-infrared absorption spectrometry. It was shown that detection limit (3s) of this method was 0.000 69%. The high beryllium beryllium-alminium alloy samples with different contents of carbon were determined 11 times, with RSDs of the determined values in the range of 2.4%-6.0%.
