鋇鐵氧磁體
英文
barium ferrite-
The effects of the different kinds of rare earths and the doping amount of them on magnetic properties of bafe, 2o19 ultrafine powders ( including the specific saturation magnetization, the specific remanent magnetization and coercive force ) were firstly discussed systematically
首次查明了鋇鐵氧體粉末的磁性能(包括比飽和磁化強度、比剩餘磁化強度和內稟矯頑力)隨稀土元素種類及其摻雜量的變化規律。The elements of ferrite magnet are ferricoxide barium strontium. ferrite has highter coercive force and highter resistance to bedemagnetized and oxidized than other non - rare earth permanent magnets. the biggest advantage of such magnet is their low cost. it is widely used from motors and loudspeakers to toys and craft etc.
鐵氧體由氧化鐵、鋇、鍶等元素組成,與其它非稀土磁鋼相比,鐵氧體的矯頑力和抗腐性都比較好,尤其它的低成本更是其它磁鋼所無法比擬的。它被廣泛應用於從電機、揚聲器到玩具、工藝品等各個領域In this paper based on hexagonal ferrites with high resonance frequency, the electromagnetic properties of the z - type ferrites in the range of 50mhz to 1ghz have been carried out and have sintered at low temperature through the gelatin spontaneous combustion
本文以具有高截止頻率的六角鐵氧體為基礎,開展了50mhz 1ghz的z型六角鋇鐵氧體電磁性能的研究,並通過凝膠自燃法實現了低溫燒結。To measure the size of ba - ferrite fine magnetic particles, electromagnetic field was employed to drive the fine magnetic particles displace in order, then scanning electron microscope ( sem ) was used to observe and measure the size of ba - ferrite fine magnetic particles
為了迅速、準確地測定鋇鐵氧體磁粉顆粒的厚度、直徑和厚徑比的統計分佈,採用對磁顆粒施加外加電磁場的方法,使各個磁顆粒的易磁化軸方向趨於一致,並用掃描電子顯微鏡觀察鋇鐵氧體磁粉顆粒。分享友人
