Spectrochemical analysis of boron carbide by powder techniques. Final report
Technical Report
·
OSTI ID:7321320
A method for the determination of impurities in boron carbide was developed using powder techniques. The elements aluminum, calcium, iron, magnesium, manganese, nickel, silicon, titanium, and vanadium were determined over concentration ranges between 10 and 24,000 parts per million. The boron carbide powder was mixed with buffers including an internal standard. These sample mixtures were excited in a direct current arc and spectra were recorded on photographic plates. Due to a lack of standard boron carbide samples, the analytical curves are based on the wet chemical analysis of six samples. Dilution with graphite was employed to extend the analytical curves of the higher levels elements (aluminum, calcium, iron, and silicon) down to 100 ppm or less.
