Description
上記の方法は以下の順次操作を含む。
2.溶融塩の150°Cでの分解(脱硝)
3.残留水分の250°C以上での焼成及び蒸留
4.混合物の焼成及び酸化
この方法は、多段の性質があり、混合物が入った容器を一つの加熱炉から他の加熱炉に移す必要があること並びに形成する焼結体の追加粉砕が必要であることの欠点を持つ。
2HNO3 +3HCOOH → 2NO+3CO2 +4H2 O
上記の反応が自己触媒反応の性質を有するので、爆発性ガス混合物の形成を伴う制御不可の反応現象が発生する可能性があり、成分の混成後、反応混合物をゆっくり最長2時間乾燥しなければならないが、これは、プロセスを断続的にし、非生産的にする。
- ローターは、4枚のブレードと溶接され、ブレード端部と壁面との隙間は、0.5mm-1.5mmである。
濃度100g/lのウラン濃度及び濃縮ギ酸とともに、1モルのHNO3 における硝酸ウラニル溶液は、室温で、硝酸イオン-ギ酸のモル比が1:3.6となるように、投入ポンプによりT形フローチョーク経由で、反応器に個別に供給される。反応器の壁面の温度は、142°Cで、受入ホッパーの壁面の温度は、145°Cである。粉末は、受入ホッパーに均等に注がれる。蛍光X線分析データによると、上記の粉末は、50重量%のギ酸塩水和物(CH2 O5 U)と50重量%の水溶性ギ酸塩(C2 H2 O6 U・H2 O)との2つの結晶相から構成される。実施例1で得られた粉末のX線回折パターンを図2に示す。図2において、●(黒い丸で示すプロット点)は、CH2 O5 U構造を持つ化合物で、■(黒い四角で示すプロット点)は、C2 H2 O6 U・H2 O構造を持つ化合物である。
