The influences of Al, Zn and Mg metals on nitridation of NbCl_5 were examined. In the NbCl_5-Al-N_2 system, NbN was formed above 500℃. After heating the powder mixture at 1100℃ for 1 h, the N/Nb ratio in the product was 0.88. The ratio was slightly higher than the theoretical value. On the other hand, in the NbCl_5-Zn-N_2 system, formation of NbZn_3 alloy was observed from 400℃ to 500℃, and NbN was formed above 700℃. After heating the powder mixture at 900℃ for 1 h, the N/Nb ratio in the product was 0.63, but. The N/Nb ratio decreased above 900℃. In the NbCl_5-Mg-N_2 system, NbN was formed above 500℃, and MgO formed from oxygen, which was present in trace amounts, was removed by washing the product with IN HCl solution. The particle size of NbN powder ranged from 0.1 to 0.3 μm. After heating the powder mixture at 1100℃ for 1 h, the N/Nb ratio in the product was 0.91. When heated at 1100℃ for 4 h, the N/Nb ratio in the product was 0.94, which was the highest value among the three reducing agents. The above results indicated that Mg was the most effective reducing agent.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"rights: 社団法人日本セラミックス協会\nrights:
