High-frequency low-loss soft magnetic ferrite material and preparation method thereof
The invention discloses a high-frequency low-loss soft magnetic ferrite material which comprises the following components in percentage by mass: 69wt%-72.0 wt% of ferric oxide, 3wt%-5.0 wt% of copper oxide, 22wt%-24.0 wt% of manganous-manganic oxide and 2wt%-4wt% of an additive, wherein theadditive is a mixture of calcium carbonate, cobaltic oxide, niobium pentoxide, titanium dioxide, nickel nitrate and bismuth trioxide, and the additive is prepared from the following components in percentage by mass: 0.05 wt %-0.15 wt % of calcium carbonate, 0.05 wt %-0.25 wt % of cobalt sesquioxide, 0.025 wt %-0.05 wt % of niobium pentoxide, 0.2 wt %-0.50 wt % of titanium dioxide, 0.05 wt %-0.25 wt % of nickel nitrate and 0.05 wt %-0.15 wt % of bismuth sesquioxide. Through arrangement of corresponding mechanisms on the rotary furnace, the sealing performance of the rotary furnace is effectively improved, the danger that surrounding workers are scalded is reduced, control over the temperature precision of the rotary furnace is improved, damage to pre-sintered materials in the rotary furnace is avoided, raw material loss of soft magnetic ferrite materials in the preparation process is reduced, and the cost consumption of a user is reduced.
本发明公开了一种高频低损耗软磁铁氧体材料，高频低损耗软磁铁氧体材料按质量百分比计包括以下成分：三氧化二铁69wt%‑72.0wt%、氧化铜3wt%‑5.0wt%、四氧化三锰22wt%‑24.0wt%、添加剂2wt%‑4wt%，添加剂为碳酸钙、三氧化二钴、五氧化铌、二氧化钛、硝酸镍和三氧化二铋的混合物，添加剂的质量百分比含量为：碳酸钙0.05wt%‑0.15wt%、三氧化二钴0.05wt%‑0.25wt%、五氧化铌0.025wt%‑0.05wt%、二氧化钛0.2wt%‑0.50wt%、硝酸镍0.05wt%‑0.25wt%、三氧化二铋0.05wt%‑0.15wt%。本发明通过回转炉上相应机构的设置，有效的提升了对回转炉的密封性，降低了周边工作人员被烫伤的危险，不仅提升了回转炉对自身温度精度的控制，还避免了回转炉内预烧材料的损坏，降低了软磁铁氧体材料在制备过程中原料的损耗，减少了使用者的成本消耗。
