Beschreibung
Zusammenfassung:	FIELD: oxide glass-like materials possessing ferromagnetic properties for electronics, magneto-optics and laser engineering. SUBSTANCE: ferromagnetic glass contains Fe2O3, NiO and ZnO in form of nickel-zinc ferrite (Ni, Zn)Fe2O4, which is just ferrite process waste at the following ratio of components, mas.%: SiO2, 35.3-45.2; Na2O, 5.3-7.2; B2O3, 10.8-26.7; Fe2O3,, NiO and ZnO in form of (Ni, Zn)Fe2O4, 35.7-40.8. EFFECT: improved magnetic characteristics of glass: residual magnetization, coercive force and saturation magnetization. 2 tbl
