技术领域
本发明涉及光电透明陶瓷材料领域，具体是一种铌酸钾钠基透明陶瓷及其制备方法。
背景技术
铌酸钾钠（K0.5Na0.5NbO3，KNN）基透明陶瓷作为固体激光介质备受关注，与单晶相比，透明陶瓷容易制备，可值得大尺寸的样品，成本低，可以实现高浓度掺杂，易于制备多层以及复合多功能陶瓷。
KNN基透明陶瓷是一种高性能的陶瓷材料，具有耐热、耐腐蚀性、极高的熔点、比较高的介电常数以及优异的光学性能等优良特性，加之其可以采用传统的陶瓷烧结方法低成本制备，因而具有重要的研究意义和应用价值。另外，KNN基透明陶瓷其在光学滤波器装置、开关、调制器、数据处理器等方面，也展现出广阔的应用前景。
目前，有一些关于稀土掺杂的KNN基透明陶瓷的研究专利报道，如“一种Er3十、Yb3十共掺LiBiO3改性的KNN基上转换透明陶瓷的制备方法”，其专利号为CNIO3613383A，在400nm~1100nm的波长阶段透光率小于40%。现有技术存在的问题是透光率还有待提高。
发明内容
为了解决上述技术问题，本发明的目的是提供一种铌酸钾钠基透明陶瓷及其制备方法，以提高铌酸钾钠基透明陶瓷的透光率。其制备方法包括配料、湿磨、烘干、预烧、二次球磨、压制成型、烧结。
实现本发明的具体技术方案如下：
步骤（1）所用原料Na2CO3 (99.8%)、K2CO3 (99%)、Nb2O5 (99.5%)、BaCO3、Bi2O3均置于120℃的烘箱中烘干5~7 h；
步骤（2）按照化学计量比称取粉料，原料装入HDPE材质的球磨瓶中，以无水乙醇为介质球磨24 h；
步骤（3）将球磨后产物取出，将烘干的粉料过100目筛后，然后在750℃下预烧6 h，升温速率为1°/min；
步骤（4）再以无水乙醇为介质球磨16~24h后烘干；
步骤（5）将烘干的粉料过100目筛后，在100 MPa的压力下压制成直径为14mm，厚度为2~3 mm的圆坯；
步骤（6）将压制好的圆坯在1140下保温3~21h烧结获得透明陶瓷。
本发明本发明与现有技术相比的优点是：BaBiO3掺杂的铌酸钾钠基透明陶瓷在这个波长阶段透光率可达75%，且物丰价廉。
