摘要
The invention relates to a deflection ring of sintered MgZn- ferrite material. In accordance with the invention, this deflection ring is characterized in that the majority of the grains of the sintered material have a monodomain structure. By virtue thereof, a relatively small heat dissipation occurs in the ring when it is used in a cathode ray tube. The average grain size of the sintered MgZn-ferrite material is preferably 2. 8 micrometers or less. MgZn-ferrite materials whose composition corresponds to the formula Mg.sub.1-z Zn.sub.z Fe.sub.2-y O. sub.4, wherein 0.1 z 0.4 and 0.01 y 0.3, have the additional advantage that they have a relatively high saturation magnetization and a relatively high electrical resistance. The invention also relates to a cathode ray tube comprising the above-mentioned deflection ring and to a mo1lding made from the above-mentioned MgZn- ferrite material.
