The ferromagnetic microcrystal glass thermoseed matierals were prepared by crystallization method. The composition of basis glass was Fe2O3-CaO-SiO2-B2O3-P2O5 system. The major phases of magnetite (Fe3O4), wollastonite (CaSiO3) and hematite (Fe2O3) were identified in the heat-treated samples by XRD patterns. Room temperature magnetic property was measured by a vibrating sample magnetometer (VSM). The morphology of the sample was observed by SEM. The effect of heat-treatment time on the magnetic properties of samples was investigated. And the results show that perfect heat-treatment time is two hours . The specific saturation magnetic moment of 26.2 A·m2·kg-1 is obtained.
