Bulletin the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 8, рр. 59-67. In Rus. The relevance research is determined by need to assess transformation materials in its natural occurrence, as well as, changes properties and products are exploited under various operating conditions. X-ray diffraction Infrared spectroscopy was used crystalline made silicon dioxide, which showed satisfactory convergence results can be recommended use world practice. Objects: artificially grown quartz, including samples synthetic with an admixture aluminum, zone-colored single crystal two ferric iron; crystals amethyst, smoky optical quartz; fused technical silicate glass; fine-grained quartzites, their micro- nano-sized fractions. Methods: electron scanning microscopy, spectral analysis, infrared spectroscopy, diffraction. Results. paper shows that based on it presence a structural ordering near zone characterizes state corresponding a-quartz phase, confidently recorded XRD FTIR methods. local disorder high-purity or quartzites having impurities defects structure arise influence external influences exploitation causes deterioration decrease crystallinity.
