Fabrication of an oriented glass-ceramics electrolyte

以含这些氧化物的熔融玻璃为原料，通过晶化工艺制备了La-Ca-Si-Al-O型氧磷灰石固体电解质。将玻璃切片在高于其晶化温度的炉中退火，以获得陶瓷固体电解质。经X射线衍射分析，该玻璃的主相为氧磷灰石，其空间群与高氧离子导体硅酸镧La_（9.33+x）Si_6O_（26+1.5x）的空间群相同。此外，在一定条件下，可以获得具有上级离子导电性的取向陶瓷。

Oxyapatite-type La-Ca-Si-Al-O solid electrolytes were fabricated from melted glasses containing these oxides via crystallization process. Sliced glass plates were annealed in a furnace at above its crystallization temperature in order to obtain ceramics solid electrolytes. According to an XRD measurement, the main phase of the crystallized glass was oxyapatite, whose space group was the same as that for a high oxide-ion conductor, lanthanum silicates, La_<9.33+x>Si_6O_<26+1.5x>,. In addition, under certain conditions, an oriented ceramics exhibiting superior ionic conductivity could be obtained.
