長距離秩序を持つTa-Te系の準結晶が実現されれば世界で初めての長距離準周期秩序をもつ12回対称準結晶の合成となる。良質な長距離準周期秩序を持つTa-Te準結晶の高温高圧合成条件の探索を行った。その結果、いずれの合成条件でもTaTe_2が安定化し、準結晶組成のTa_<1.6>Teは合成されなかった。熱力学的安定条件下では長距離秩序を持つ準結晶相が安定に存在しない可能性を示す結果となった。

The long-distance separation order is based on the standard Ta-Te system. In the beginning of the world, the long-distance system has a long-range cyclical order. 12 cycles have been measured and synthesized. High temperature and high temperature synthesis conditions of high temperature and high temperature are studied in the long-term cycle order, Ta-Te preparation crystal and high temperature synthesis conditions. Test the results, compare the synthesis conditions, stabilize the TaTe_2, prepare the crystal to form the Ta_<1.6>Te, synthesize the Ta_<1.6>Te, and prepare the synthesis conditions. Under the condition of mechanical stability, the long-distance separation order depends on the standard crystal phase stability. The possibility of stability indicates that the results are not satisfactory.
