Kvantitativní stanovení amorfního podílu v krystalických materiálech použitím rentgenové práškové difrakce

Abstract

Quantitative assessment of the amorphous content in crystalline materials has become an integral part of many industries. After an initial description of the general principles of X-ray, the theory of X-ray diffraction and diffraction methods in the first part of the bachelor's thesis, the attention is given to the possibility of determination of the amorphous content with the data from X-ray powder diffractometry. Various methods and their principles are introduced, including the evaluation of their advantages and disadvantages. In the final part of the thesis, the amorphous content in samples of blast-furnace slag is determined. Blast-furnace slag arises as a by-product of metallurgical processes. In the pursuit of sustainable development with the emphasis on the elimination of undesirable environmental effects, a new application for these waste materials is sought. Due to its latent hydraulic properties, which are strongly dependent on the amorphous content, blast-furnace slag seems to be an adequate additive or even a substituent of binder materials, such as cement. Therefore, it can be used in various sectors of the construction industry.
