Preparation of Ba-ferrite containing glass-ceramics in BaO-Fe2O3-SiO2

Creators

Description

Ba-ferrite (BaFe12O19) containing glass-ceramics have been prepared from the glass in BaO-Fe2O3-SiO2 through a novel 2 step crystallization method in order to manufacture the magnetic memory disk without deformation. It is revealed that the glass pre-crystallized prior to secondary crystallization shows no shape deformation during heat-treatment and also exhibits better magnetic properties compared with the conventional 1 step crystallized glass
