Preparation method for NiCuZn ferrite material
The invention relates to a preparation method for a NiCuZn ferrite material and belongs to the technical field of electronic materials. The preparation method comprises the following steps: 1) preparing materials according to a formula: adopting a formula of Ni<0.52-x>CoCu0.1Zn0.4Fe1.98O3.99, wherein x is 0 to 0.40; 2) carrying out first ball-milling: uniformly mixing powder according to the formula in a ball mill for 1-3 hours, wherein the ball-milling medium is steel balls; 3) carrying out pre-sintering: drying the ball-milled material and pre-sintering the ball-milled material for 2-4 hours in a furnace at 900 DEG C; 4) carrying out doping: adding the following doping agents: 0.001-0.80wt% of BaTiO3, 0.01-0.20wt% of CaCO3, 0.01-0.20wt% of V2O5 and 0.001-0.20wt% of Bi2O3; 5) carrying out second ball-milling: carrying out ball-milling for 4-8 hours, wherein the gain size of the final powder after ball-milling is 0.6-1.0 [mu]m; 6) carrying out molding: adding 10-16wt% of an organic bond according to the weight ratio, uniformly mixing the mixture, and after granulation, pressing the granular powder into blanks on a press; and 7) carrying out sintering: putting the blanks in the step 6) in a sintering furnace, and carrying out heat-preserved sintering on blanks for 2-6 hours at 960-1080 DEG C. The NiCuZn ferrite material prepared by the invention has excellent characteristics of being high in saturated saturation flux density, high in Curie temperature, low in dielectric loss, low in ferromagnetic resonant linewidth and the like.
