式(II)において、xは、上記の通りである。
− ヨードアパタイトの合成および緻密化を単一工程で行うことができる;
− このような合成および緻密化を十分に低い温度かつ十分に短い時間で行うことにより、反応物として用いられるヨード化合物の拡散およびヨウ素の揮発のリスクを排除することができ、結果として、不浸透性の収納マトリクスに頼る必要がない;
− さらに、非常に高度に圧縮されたヨードアパタイトが得られる。すなわち、深い地層型用地における放射性ヨウ素の調整および貯蔵のためのヨードアパタイトに関して要求される基準を満たす、97%を超える緻密化度を有するヨードアパタイトが、反応収率100%またはそれに近い値で得られる。
最初に、Pb3(VO4)1.6(PO4)0.4の組成を有するリンバナジウム酸鉛が、機械的混合により予め均一化された、酸化鉛、五酸化バナジウムおよびリン酸水素二アンモニウムの化学量論的混合物を、空気中、1000℃の温度で1時間か焼することにより調製される。反応は以下のとおりである:
3PbO + 0.8V2O5 + 0.4(NH4)2HPO4 →
Pb3(VO4)1.6(PO4)0.4 + 0.6H2O + 0.8NH3
2NaI(aq) + Pb(NO3)2(aq)
→ PbI2(s) + 2NaNO3(aq)
リンバナジウム酸鉛/ヨウ化鉛混合物の反応性焼結が、Sumitomo, Dr Sinter L型フラッシュ焼結装置を用いて行われる。この装置は以下を備える:
・ リンバナジウム酸鉛/ヨウ化鉛混合物試料が配置されるグラファイトダイ;および
・ 上記ダイに作用(apply)する、パルス化直流電源に接続された2つの電極。
