摘要

以含铁纳米多孔玻璃为原料，在MnCl2和H2C2O4水溶液中浸渍含磁铁矿基质，生成锰氧化物MnxOy (x = 1,2,3;y = 1,2,3,4)，这是由于掺杂剂(MnC2O4)的反应产物热裂解的结果。研究了合成的CMs的化学(元素)和物相组成、铁和锰的配位态以及磁性态的特征，并与纳米多孔基质的特征进行了比较。

Synthesis and Investigation of New Vitreous Materials with Two Magnetic Subsystems (Fe3O4 and MnxOy)

New vitreous composite materials (CMs) with two magnetic subsystems are synthesized by impregnation magnetite-containing matrices from iron-containing nanoporous glasses in aqueous MnCl₂ and H₂C₂O₄ solutions and the subsequent formation of manganese oxides Mn_xO_y (x = 1, 2, 3; y = 1, 2, 3, 4) inside the pore space of the matrices as a result of thermolysis of the reaction product of the dopants (MnC₂O₄). The chemical (elemental) and phase compositions, the valence-coordination state of iron and manganese, and the characteristics of the magnetic state of the synthesized CMs are studied and compared with the characteristics of nanoporous matrices.
