摘要
Mossbauer spectroscopic studies have been performed on glass ceramics in which barium and strontium hexaferrites have been crystallized as a major magnetic phase. The crystallization process of the different magnetic phases has been studied by suitable heat treatments of the initial glass compositions 35BaO-4OB2O3-25Fe2O3, 35SrO-4OB2O3-25Fe2O3 and 47SrO-28B2O3-25Fe2O3. The nucleation and growth times have been varied and Mossbauer spectra of differently heat-treated samples analysed to determine the optimum composition and heat treatment required for the good growth of the hexagonal ferrites BaM and SrM.
