Description
ホウ素をドープしたルチル型酸化チタンは、放電プラズマ焼結法により得られる。具体的には、TiO2にB2O3粉末を添加した原料粉末を、5Paの真空度において、1200℃に加熱して焼結することにより直径10mmのペレット状の焼結体を得た。図示は省略するが、得られた焼結体の結晶構造をX線回折により測定したところ、ルチル型であることを確認した。また、室温において導電性があることも確認した。
Claims (2)
- ホウ素をドープしたルチル型酸化チタンであって、100K〜300Kの温度域におけるゼーベック係数が500μV/K以上である熱電変換材料。
- ホウ素のドープ量が5×10 18 cm −3 〜5×10 19 cm −3 である特徴とする請求項1に記載の熱電変換材料。
