Preparation process of high-frequency low-loss high-resistivity nickel-zinc ferrite material
The invention discloses a primary sintering process of high-frequency low-loss high-resistivity nickel-zinc ferrite, which is characterized by comprising the following steps: mixing iron oxide, nickeloxide and zinc oxide in a certain proportion, and adding vanadium pentoxide in a certain proportion as a sintering aid and silicon dioxide in a certain proportion as an insulating medium; by taking an ethanol solution as a dispersing agent, carrying out ball milling on the obtained mixture, then drying and granulating the mixture, carrying out compression molding, finally carrying out programmedheating, glue discharging and sintering in a muffle furnace, and cooling a product to room temperature, thereby obtaining the high-frequency low-loss high-resistivity nickel-zinc ferrite material. According to the process, the nickel-zinc ferrite material which is low in loss, high in resistivity, round and uniform in crystal grain, compact and free of holes under high frequency can be obtained without presintering and secondary ball milling, and meanwhile, the production efficiency of the product is improved.
本发明公开了一种高频低损耗高电阻率镍锌铁氧体的一次烧结工艺，其特征在于：将一定比例的氧化铁、氧化镍、氧化锌混合，并在其中加入一定比例的五氧化二钒作为烧结助剂和一定比例的二氧化硅作为绝缘介质；以乙醇溶液作为分散剂，将上述获得的混合物进行球磨，随后烘干、造粒、并压制成型，最后在马弗炉中程序升温排胶烧结，冷却至室温即得到高频低损耗高电阻率镍锌铁氧体材料，本工艺无需预烧结及二次球磨即可获得一种高频下具有低损耗，高电阻率，晶粒圆润均匀，致密无孔洞的镍锌铁氧体材料，同时提高产品的生产效率。
