Abstract
Structural features of mineral crystal phases and defectiveness of bismuth organosiliconate crystals are inspected at various temperatures of treatment (from 100 to 500°C). X-ray diffraction enables evaluation of crystal lattice periods from spectrograms recorded in СuKα radiation. The approximation analysis of the broadening of the most intense diffraction lines in crystals from (hkl) crystallographic indices allows one to determine the coherent domain sizes and microdistortions Δа/а of a crystal lattice. It is found that exposure of the Na2O–Bi2O3–SiO2 system (NBS material) to temperatures of 300–500°C leads to a decrease in amorphism, microdistortions, and the density of dislocations in a crystal lattice of Bi12SiO20 sillenite. The formation of a denser structure of sillenite crystal with higher X-ray density (9.210 g/cm3) and greater cubic crystal lattice parameter (a = 10.1335 Å) is detected. The presented Bi12SiO20 material can be used as a gamma and protective filler of radiation protective polymers and in the design of electro-and magneto-optical laser radiation modulators.
