Nickel-zinc-copper ferrite powder and preparation method thereof
The invention relates to nickel-zinc-copper ferrite powder and a preparation method thereof. The preparation method comprises the following steps: mixing Fe2O3 powder, CuO powder, ZnO powder and NiO powder with the particle sizes of 0.18-0.52 through adding water, so as to obtain slurry; drying the slurry, so as to obtain mixed powder; calcining the mixed powder at the temperature of 700-900 DEG C for 4-6 hours, so as to obtain the nickel-zinc-copper ferrite powder. According to the invention, the particle sizes of the nickel-zinc-copper ferrite powder prepared through the preparation method are mainly distributed between 0.4 micron and 1.0 micron, and the nickel-zinc-copper ferrite powder is enabled to have relatively low sintering temperature; the nickel-zinc-copper ferrite powder prepared through the preparation method has better low temperature co-firing property, and can be well co-fired with other ceramic materials or silver electrode in a matching manner.
