style="text-indent:25px">釹磁鐵（Neodymiummagnet）也稱為釹鐵硼磁鐵（NdFeBmagnet），是由釹、鐵、硼（Nd2Fe14B）形成的四方晶系晶體。于1982年，住友特殊金屬的佐川真人發(fā)現(xiàn)釹磁鐵。這種磁鐵的磁能積（BHmax）大于釤鈷磁鐵，是當(dāng)時(shí)全世界磁能積較大的物質(zhì)。后來(lái)，住友特殊金屬成功發(fā)展粉末冶金法（powdermetallurgyprocess），通用汽車公司成功發(fā)展旋噴熔煉法（melt-spinningprocess），能夠制備釹鐵硼磁鐵。這種磁鐵是現(xiàn)今磁性僅次于相對(duì)零度鈥磁鐵的永久磁鐵，也是較常使用的稀土磁鐵。釹鐵硼磁鐵被普遍地應(yīng)用于電子產(chǎn)品，例如硬盤(pán)、手機(jī)、耳機(jī)以及用電池供電的工具等。為了避免腐蝕的損害，使用時(shí)需要在永磁材料表面做保護(hù)處理，例如用金、鎳、鋅、錫進(jìn)行電鍍，以及表面噴涂環(huán)氧樹(shù)脂等。</p><p style="text-indent:25px">近年來(lái)，釤鈷材料的應(yīng)用領(lǐng)域在不斷的擴(kuò)大，目前主要釤鈷材料為節(jié)能燈用釤鈷材料、顯示用釤鈷磁材料和特種光源用釤鈷磁材料。隨著國(guó)家政策扶持力度的不斷加強(qiáng)，到2015年，釤鈷材料的市場(chǎng)需求更是逐年增加。但是，因?yàn)槭艿饺蚪?jīng)濟(jì)低迷的影響，節(jié)能燈市場(chǎng)需求不足，加上2011年的部分囤貨需要消化，2012年全球燈用釤鈷熒光粉產(chǎn)量出現(xiàn)大幅度的下滑，一直降到4500噸，估計(jì)2013年將繼續(xù)低迷，降至4200噸左右。從長(zhǎng)期來(lái)看，隨著我國(guó)推廣節(jié)能燈方面政策的出臺(tái)及熒光粉價(jià)格的降低，未來(lái)燈用熒光粉的需求可能會(huì)逐漸恢復(fù)。隨著全球淘汰的白熾燈計(jì)劃的實(shí)施，節(jié)能燈將會(huì)迎來(lái)新的發(fā)展機(jī)遇。但是因?yàn)槭茚熲挻艃r(jià)格上漲等因素的影響，歐美等多地使用的燈用釤鈷熒光粉已經(jīng)停產(chǎn)或產(chǎn)量很少，未來(lái)中國(guó)資源型燈用熒光粉企業(yè)可能更具競(jìng)爭(zhēng)力及抗風(fēng)險(xiǎn)能力。很多人都知道磁鐵的特性，可以吸收鐵。</p><div

style="text-indent:25px">釹鐵硼主要優(yōu)點(diǎn)：性價(jià)比高，并且在機(jī)械方向上擁有不錯(cuò)的特性缺點(diǎn)在于：居里溫度點(diǎn)偏低，同時(shí)溫度特性較差，并容易發(fā)生粉化腐蝕，必須通過(guò)調(diào)整其化學(xué)成分和采取表面處理方法（如鍍鋅等）使化學(xué)性能上得到改進(jìn)，才能達(dá)到我們需要的實(shí)際應(yīng)用要求。而鐵氧體永久磁鐵是一類擁有鐵磁性的金屬氧化物。就電特性來(lái)說(shuō)，鐵氧體永久磁鐵的電阻率相比于比金屬與合金磁性材料來(lái)要大得多，并有稍偏高的介電性能。釹鐵硼永久磁鐵和鐵氧體永久磁鐵磁鐵的區(qū)別主要有以下幾點(diǎn)：1.鐵氧體永久磁鐵性能不如釹鐵硼永久磁鐵。2.價(jià)格上.鐵氧體永久磁鐵的要比釹鐵硼永久磁鐵磁鐵便宜很多。3.釹鐵硼永久磁鐵耐溫很好，而普通的釹鐵硼永久磁鐵通常只能80度，超過(guò)了這個(gè)工作溫度就會(huì)出現(xiàn)退磁情況。4.鐵氧體永久磁鐵穩(wěn)定性非常好，它本身是氧化物，很穩(wěn)定，釹鐵硼永久磁鐵是合金，及其容易氧化、必須做涂層保護(hù)。由于釹鐵硼磁鐵磁性較強(qiáng)、可加工性好，價(jià)格適中，是工業(yè)生產(chǎn)中運(yùn)用較廣的磁鐵。溫州辦公自動(dòng)化磁鐵哪家好</p><p
