一种光伏产业逆变器用软磁铁氧体材料及其制备工艺
技术领域
本发明涉及软磁铁氧体磁芯技术领域，特别涉及一种光伏产业逆变器用软磁铁氧体材料。
背景技术
在并网逆变器中，起绝缘及功率变换作用的器件是高频变压器，高频变压器必须使用高饱和磁通密度(Bs)、低功率损耗(Pcv)软磁铁氧体磁芯。为了进一步提高并网逆变器转化效能，研发优质性能的高饱和磁通密度(Bs)、低功率损耗(Pcv)软磁铁氧体材料是国内外相关企业、高校和研究院所的热门课题。
软磁材料是本身不具磁性，但在磁场中就会被磁化获得磁性，离开后又失去磁性的一种具有高电阻率、低损耗、较高磁导率的磁性材料。由于软磁材料的优异特性因此被广泛应用于各种电子与电工设备中。其中占据大部分市场的主要包括MnZn和NiZn铁氧体两大系列。软磁铁氧体材料应其用途广且成本低产量大，被称为电子工业的基础材料。MnZn铁氧体电子元器件一般具有高的起始磁导率μi、高品质因数Q、高稳定性DF、au、较高的截止频率fr。是最重要的国民软磁铁氧体材料，应用量将近占据软磁铁氧体总体的三分之二。
MnZn铁氧体广泛用于电子、通讯领域作为能量存储和转换用材料。电子器件的小型化、高速化、高输出功率要求MnZn铁氧体器件能够在大电流下即较高的直流偏置下仍然正常工作。但与软磁金属材料相比，铁氧体属亚铁磁性材料。所以MnZn铁氧体的主要缺点是其饱和磁通密度(Bs)较低，通常只有金属磁粉心的二分之一到三分之一，使得MnZn铁氧体抗直流偏置能力比软磁金属材料差。
因此，需要研究一种在高温和低温均具有高饱和磁感应强度的、低损耗的光伏产业逆变器用软磁铁氧体材料。
发明内容
本发明的目的在于提供一种在高温和低温均具有高饱和磁感应强度的、低损耗的光伏产业逆变器用软磁铁氧体材料。
本发明的上述技术目的是通过以下技术方案得以实现的：
一种光伏产业逆变器用软磁铁氧体材料，包括预烧结主料和复合混合料，按重量分数计，所述预烧结主料包括以下组分和配比：Fe2O370-75份、Mn3O420-25份、ZnO 3-8份、NiO 0.3-0.5份，复合混合料包括以下组分和配比：SiO20.002-0.005份、BaRuO30.001-0.002份。
作为本发明的进一步设置，按照重量份数计，所述预烧结主料中还包括：V2O50.001-0.002份。
作为本发明的进一步设置，按照重量份数计，所述预烧结主料还包括：Nb2O50.001-0.003份。
作为本发明的进一步设置，按照重量份数计，所述复合混合料还包括：高硅氧玻璃纤维0.003-0.005份。
作为本发明的进一步设置，所述预烧结主料制备步骤如下：将Fe2O3、Mn3O4、ZnO原料在球磨机中研磨至微米级，烘干后，然后预烧结一段时间，取出后在500℃-700℃温度下趁热与剩余原料共混，进行二次球磨至粒径小于1μm，烘干后即得预烧结主料。
作为本发明的进一步设置，光伏产业逆变器用软磁铁氧体材料的制备工艺包括如下步骤：按配方配比称取原料，先将复合混合料球磨至纳米级，然后再将预烧结主料和复合混合料共混，送入球磨机中研磨，研磨后烘干后造粒、压制、烧结成型，即得光伏产业逆变器用软磁铁氧体材料。
本发明的有益效果是：
1.本发明的光伏产业逆变器用软磁铁氧体材料为MnZn铁氧体，采用特殊的反应主料和复合混合料，结合采用特殊的干法光伏产业逆变器用软磁铁氧体材料的制备工艺制备出高饱和磁通密度、低磁通密度饱和后功率损耗的软磁铁氧体材料。
2.MnZn铁氧体的亚磁性是来源于A、B位置上的磁性离子磁矩不能相互抵消的相互作用，本发明的预烧结主料中添加有掺杂物质NiO，Ni2+能有效占据MnZn磁铁内部B位置，原来在B位置的Fe3+则进入A位置，提高铁氧体中Fe3+-O-Fe3+的数量，有效提高Fe3+-O-Fe3+交换作用，有效提高软磁铁的在高温下的饱和磁通密度。
3.本发明在复合混合料中还添加了高硅氧玻璃纤维，高硅氧玻璃纤维能在烧结时熔化成流动态，在烧结环境压力为0.05-0.07MPa的条件下，流动态的高硅氧玻璃纤维能在压力的条件下渗透至软磁铁内部，填补材料内部的孔隙，有效提高软磁铁的密度，从而有效提高软磁铁的饱和磁通密度。
4.本发明的复合混料中的BaRuO3的立方结构具低自旋的铁磁基态，在软磁铁制备过程中均匀分散在软磁铁中，自旋性铁磁基态及自身的自选轨道耦合较高的特性能有效提高磁矩力，有效提高软磁铁材料中的饱和磁通密度。
