The glass crystallization method is shown to be suitable for preparing BaFe sub(12-2x)Co sub(x)Ti sub(x)O sub(19) powders with a nearly perfect crystallographic structure and a narrow particle size distribution. The dependence of the specific magnetization, the coercivity, and the particle size distribution on both the annealing temperature and the Co-Ti content correlate in a characteristic way. The coercivity of the hexaferrite magnetic tapes is more than 8 x 10 super(3) A/m higher than for the the corresponding powders.
