Preparation method of highly transparent polycrystalline BaAl4O7 ceramic optical fiber
The invention discloses a preparation method of a highly transparent polycrystalline BaAl4O7 ceramic optical fiber, Al2O3-BaO precursor glass without a glass network former is prepared by a laser melting-pneumatic suspension method, and the raw materials comprise BaCO3 and Al2O3 according to a molar percentage of 1: (1.5-4). According to the preparation method, Al2O3-BaO precursor glass without a glass network former is prepared, fiber core glass is prepared through a glass optical fiber drawing technology, finally, the single-phase micron-scale BaAl4O7 non-cubic phase transparent polycrystalline ceramic optical fiber is prepared for the first time through one-step heat treatment, and the traditional concept that the non-cubic phase micron structure ceramic optical fiber is difficult to be transparent is broken through; the method is simple and efficient in process, and the prepared transparent ceramic optical fiber has the advantages of high crystallinity, high luminous efficiency and the like.
本发明公开了一种高度透明的多晶BaAl4O7陶瓷光纤的制备方法，采用激光熔融‑气动悬浮方法制备不含玻璃网络形成体的Al2O3‑BaO前驱体玻璃，包括的原料及摩尔百分比为BaCO3：Al2O3=1：（1.5‑4）。本发明制备了不含玻璃网络形成体的Al2O3‑BaO前驱体玻璃，并通过玻璃光纤拉制技术制备纤芯玻璃，最后，通过一步热处理首次制备了单相、微米尺度的BaAl4O7非立方相透明多晶陶瓷光纤，打破了非立方相微米结构陶瓷光纤难以透明的传统观念；且本发明方法工艺简单，高效，且制备的透明陶瓷光纤具有结晶度高，发光效率高等优点。
