Abstract


Chemical composition and structural-morphological characteristics of the original chrysotile asbestos and fibers that make up the lime-siliceous thermal insulation products are defined by methods of atomic spectral analysis, scanning electron microscopy with energy analysis in the selected area, derivatography, X-ray analysis, the low-temperature nitrogen adsorption-desorption and optical spectroscopy. During the impact of technological methods used for the manufacture of lime-siliceous thermal insulation products, chrysotile asbestos fibers are partially destroyed, surface of the fibers is corroded and covered with a layer of calcium carbonate and other impurities of crystalline and amorphous phases.

Keywords


chrysotile asbestos fibers; lime-siliceous thermal insulators; methods of structural analysis
