摘要：
Glasses of the xFe2O3·(100−x)[B2O3·SrO] system, with 0 ≤ x ≤ 30 mol% were studied by X-ray diffraction, density, optical microscopy and FT-IR spectroscopy measurements. The X-ray patterns for the prepared system show that vitreous phase is present only in the sample with x < 40 mol%. For x ≥ 40 mol% in the studied samples is evidenced crystalline phase of Fe2O3. SEM measurements for the sample with x = 40 mol% shows that there are formed Fe2O3 microcrystallites with 10–20 μm dimension. FT-IR spectroscopy measurements shown that BO3 and BO4 are the main structural units of the glass system and the iron ions are located in the glass network.
