HEXAGONAL MAGNETIC FERRITE PIGMENT FOR HIGH DENSITY MAGNETIC RECORDING APPLICATIONS
摘要
The present invention provides a hexagonal magnetic ferrite pigment suitable for high density magnetic applications. The pigment is characterized by small particles size, a modified magnetoplumbite structure, and relatively high magnetic moment. The pigment is capable of being prepared by firing suitable precursor particles in air at temperatures below 850 DEG C.
