| Outline of Final Research Achievements |
We have prepared the highly c-axis-oriented polycrystalline material of apatite-type La9.33+2xGe6O26+3x by isothermal heating of the randomly grain-oriented ceramics material and gases at high temperatures. In our previous studies, we reported the formation of highly grain-aligned polycrystalline lanthanum silicate oxyapatite (La9.33+2xSi6O26+3x) by the solid-state reactive diffusion. The present study reports, for the first time, the successful preparation of the grain-aligned polycrystalline material, using the same technique, between solid and gases. The authors think that one of the most significant implications of this research is that we successfully extended the reactive diffusion system from solid-solid to those including solid-gases in the preparation of grain-aligned ceramics. The present solid-gas interaction technique could be widely applicable to the other grain-aligned materials.
