Phase Composition and Catalytic Activity of Nanostructured Materials Based on Solid Component of Welding Aerosol

Abstract:

The comparison of the phase compositions and catalytic properties of the solid components of welding aerosol (SCWAs) obtained as a result of metal welding by two types of electrodes, ANO-4 and TsL‑11 was made. Their phase compositions were investigated by X-ray diffraction phase analysis, IR spectroscopy, and pH-metry. The catalytic properties of SCWAs were studied in the low-temperature reaction of ozone decomposition. Both SCWA samples were found to purify the ozone-air mixtures (OAM) from ozone at its concentration of 1 mg/m³ to the levels below the maximum permissible concentration (MPC_O3) however the protective time of SCWA-ANO-4 (50 h) was higher than that of SCWA-TsL-11 (3 h) because of the differences in their compositions
