中文摘要:
      分别以BaO、TiO2和La2O3、Nb2O5为原料采用火焰喷淬法制备了不含网络形成体的BaTi2O5(BTO)和35La2O3-65Nb2O5(LNO)玻璃微球。所有BTO为透明的、表面光滑、无结晶痕迹的玻璃微球,粒径分布集中在8~40 μm,且具有较低的非晶形成能力;而大部分的LNO为透明的、具有光滑表面的玻璃微球,粒径分布集中在10~40 μm,少量粒径较大的LNO微球表面粗糙,存在微米级LaNbO4和LaNb3O9晶粒。计算结果显示BTO和LNO玻璃微球均具有高折射率,分别为2.20和2.23,是非常有应用前景的窗口、镜头以及反光标志膜材料。

英文摘要:
      The BaTi2O5 (BTO) and 35La2O3-65Nb2O5 (LNO) amorphous microspheres without conventional network-forming oxides were fabricated by a containerless flame-spraying technique. The results showed that transparent BTO and LNO glass microspheres were successfully prepared. All the BTO glass microspheres have smooth surfaces and no crystalline traces, indicating they are amorphous glass with diameters ranging from 8 to 40 μm. Most of the LNO glass microspheres have diameters of 10 to 40 μm, which are amorphous glass with smooth surfaces. And a small number of LNO microspheres have large particle diameters, which possessing micron-sized grains on their surfaces. The BTO and LNO glass microspheres have high refractive index of 2.20 and 2.23, respectively, which are very promising to be applied as window, lens and reflection film materials.
