(71)Preparation and characterization of simulated waste borosilicate glasses including phosphorus

*Takayuki Nagai1, Kennichi Sasage1, Takehiko Inose2, Seiichi Sato2, Kiyoshi Hatakeyama3 (1. JAEA, 2. Inspection Development Co., 3. E&E Techno Service Co.)

Keywords:vitrification, borosilicate glass, simulated waste borosilicate glass including phosphorus, immersion test

P添加ガラス原料に模擬廃液を混合溶融して模擬廃棄物ガラスを作製し,浸出試験による長期化学的安定性を評価した結果,Mo溶出を抑える効果があることを確認した.また,ガラス徐冷時の結晶化挙動等を評価した結果,P添加ガラスの結晶化挙動は現行ガラス組成と同等であることを確認した.
