Homogene Keramikfasern mit magnetischen Eigenschaften

Homogeneous ceramic fibres consist of magnetite, ferrite and/or spinel. Also claimed is the production of the above fibres, comprising: (a) forming a stable sol, in which a metal compound having organic ligands containing oxygen, nitrogen and/or sulphur is dissolved in an organic solvent containing nitrogen, oxygen and/or sulphur; (b) adjusting the sol to a viscosity for pulling fibres; (c) pulling fibres from the sol; (d) drying; and (e) pyrolysing the fibres and heating to a temperature, at which the required magnetic crystal structure is formed. ADVANTAGE - Pure ceramic homogeneous fibres with magnetic properties are produced.
