Alを添加した酸化鉄を、以下に示す共沈法(尿素法)にて調製した。先ず、超音波で5分間脱気した水100L中に、Alイオンが全金属イオンの3mol%となるように、硝酸鉄(III)九水和物(Fe(NO3)3・9H2O)3.88molと、アルミニウムの硝酸塩(Al(NO3)3・9H2O)0.12molと、沈殿剤として尿素100molを加えて溶解させた。混合溶液を攪拌しながら90℃に加熱し、3時間同温度に保持した。反応終了後、48時間放置し、沈殿させ、吸引ろ過を行った。得られた沈殿物(BET比表面積52.1m2/g、平均粒子径0.1μm)を80℃で24時間乾燥して、その後300℃で3時間、500℃で10時間空気焼成を行った。このようにして得られたAl添加酸化鉄をペレット状に成形した後、250g秤量した(すなわち、生成物が全てFe2O3とAl2O3からなっているとした場合、金属鉄(Fe)170g含有)。
酸化鉄の調製時に、Alの代わりにTi、Zr、V、Nb、Cr、Mo、Ga、Mg、Sc、Ni、Cu、Nd、Rh、Ir、Ru、Pd、Pt及びAl−Pdを添加した以外は、実施例1と同様の手順にて実験を行った。カートリッジ内に空気を吸気してから20分後のガス濃度を測定し、その結果を表2に示す。表1で分かるように窒素以外の不純ガスとして、水素、一酸化炭素、二酸化炭素の最も高い濃度が観測されるのが、吸気から20分後のため、それぞれ添加物での評価結果の代表値として、比較することができる。
酸化鉄の調製時にAlを添加しなかった以外は、実施例1と同様の手順にて実験を行った。その結果を表2に示す。
カートリッジをファンにて送風冷却した以外は、実施例1と同様な手順にて実験を行った。この際、カートリッジ内の最高温度と、酸素濃度が1%に達するまでの窒素発生量を測定した。これらの結果を表3に示す。
カートリッジを厚さ10mmのセラミックボートにて断熱した以外は、実施例1と同様な手順にて実験を行った。また、カートリッジ内の最高温度と、酸素濃度が1%に達するまでの窒素発生量を測定し、これらの結果を表3に示す。
