Influence of melting temperature on iron ions behavior in B2O3–BaO–Fe2O3 glasses studied by magnetic susceptibility

Abstract Magnetic susceptibility measurements have been performed on x Fe 2 O 3 ·(100− x )[3B 2 O 3 ·BaO] glasses with 0 x ⩽50 mol% prepared at 1200 ° C and 1250 ° C equilibration melting temperatures. The temperature dependence of the magnetic susceptibility indicate that in case of these two series of glasses the distribution, valence states and the magnetical interactions of the iron ions in 3B 2 O 3 ·BaO glass matrix depend on both Fe 2 O 3 concentration and melting temperature.
