Determination of beryllium in modern aviation materials by atomic emission spectrome-try with inductively coupled plasma
Research on selection of sample preparation conditions for various beryllium-bearing aviation materials and selection of analytical lines for different ranges of Be content in these materials was carried out. The measurement technique of the mass fraction of beryllium in aviation materials by atomic emission spectrometry with inductively coupled plasma (ICP-AES) in combination with microwave sample preparation was developed. The technique allows determining both high (more than 2,5% wt.) and low (0,0001% wt.) concentrations of beryllium. It has been shown that ICP-AES technique is less long and labour-intensive and safer as compared with gravimetry technique. Work is executed within implementation of the complex scientific direction 8.6. «Elinvar, wear-resistant alloys and high-strength beryllium-bearing steels for devices and units» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
