The Effect of Thermoradiation Treatment on the Structure of Potassium Aluminoborate Glasses with Iron Oxide Additives

Abstract

Glasses of K $${}_{2}$$ O $$\cdot$$ Al $${}_{2}$$ O $${}_{3}\cdot$$ B $${}_{2}$$ O $${}_{3}$$ composition with Fe $${}_{2}$$ O $${}_{3}$$ additives from 0.1 to 3.0 wt $$\%$$ subjected to thermoradiation treatment at irradiation temperatures of 423, 473, 523, and 573 K in a $${}^{60}$$ Co gamma field at a dose rate of 236 R s $${}^{-1}$$ have been structurally studied. X-ray diffraction spectra revealed the crystal structure of nanosized inclusions of iron oxides, magnetite phase, and hematite phase in grid glass. SEM has shown that gamma irradiation at doses of $$(0.3-1.0)\times 10^{6}$$ R reduces the initial surface roughness from 0.5 to 0.1 $$\mu$$ m, and thermoradiation treatment significantly polishes the surface.
