Large-grain-size LiZnTi ferrite and preparation method thereof
The invention discloses LiZnTi ferrite with a large grain size and a preparation method thereof. The LiZnTi ferrite comprises the following raw material components in percentage by mass: 99.25 to 99.75 wt% of a main component and 0.25 to 0.75 wt% of an additive. The main component comprises the following components in percentage by mass: 72.3 to 75.3 wt% of Fe2O3, 5.3 to 6.5 wt% of Li2CO3, 10.2 to 10.4 wt% of ZnO, 4.7 to 4.9 wt% of TiO2 and 3.0 to 7.4 wt% of nano-CuO. The component of the additive is LBSCA glass. The preparation method has the beneficial effects that proper nano-CuO particles and the low-melting-point glass additive are added in the presintering stage of the LiZnTi ferrite, so the sintering temperature is effectively reduced to 900 DEG C; and meanwhile, the ferrite can keep good magnetic performance of the LiZnTi ferrite like a large-grain microstructure obtained by high-temperature sintering.
本发明公开了一种大晶粒尺寸的LiZnTi铁氧体及其制备方法，该LiZnTi铁氧体包括以下质量百分含量的原料组分：99.25～99.75wt％的主成分、0.25～0.75wt％的添加剂，其中所述主成分按质量百分比包括72.3～75.3wt％的Fe2O3、5.3～6.5wt％的Li2CO3、10.2～10.4wt％的ZnO、4.7～4.9wt％的TiO2、3.0～7.4wt％的纳米CuO，所述添加剂成分为LBSCA玻璃。本发明的有益效果是：通过在LiZnTi铁氧体预烧阶段加入合适的纳米CuO颗粒以及低熔点玻璃添加剂，有效地将烧结温度将至900℃，同时该铁氧体能像高温烧结获得的大晶粒的微结构同时保持了LiZnTi铁氧体良好的磁性能。
