| Research Abstract |
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.
