Structural and redox effects in iron-doped magnesium aluminosilicates

The results revealed that faster pulling rates promote formation of isolated iron cations in the glass forming network. The crystallization process is strongly affected by lower pulling rates. LFZ method shows good prospects for studying the crystallization mechanisms in silicate-based glasses with additions of redox-active cations, by providing flexibility in tuning their oxidation state and crystalline/amorphous conditions.
