RADIOACTIVE SUBSTANCE ADSORPTION CERAMIC FOR DISPOSING OF RADIOACTIVE SUBSTANCE SAFELY
PROBLEM TO BE SOLVED: To provide a radioactive-substance-adsorption porous ceramic material that has high performance of adsorbing radioactive substances and is excellent in a dry and wet resistance.SOLUTION: A ceramic adsorption agent is formed by carrying out first burning of a compound including: a radioactive substance adsorption agent made of one type or a plurality of types of components of inorganic substances, such as a radioactive substance adsorption material of diatomaceous earth, zeolite, calcium phosphate, titanium oxide and the like, excellent in performance of adsorption of radioactive substances, as a main raw material; a caking additive; and a burning auxiliary material and the like. After having undergone adsorption processing, the ceramic adsorption agent is further burned at a high temperature, thereby enabling being disposed of in the underground and the like for a long term safely.SELECTED DRAWING: None
【課題】放射性物質の吸着能力が高く、乾湿抵抗に優れた放射性物質吸着多孔質セラミックス材を提供する。【解決手段】放射性物質の吸着性が優れた無機質物質、例えば、珪藻土、ゼオライト、リン酸カルシウム、酸化チタン等の放射性物質吸着材の一種または複数の成分からなる放射性物質吸着剤を主原料とし、粘結材及び焼成助材等からなる混合物を１次焼成してなる。該セラミック吸着剤は、吸着処理を行った後に、さらに高温で焼成することによって、地中などに長期間、安全に廃棄することを可能にする。【選択図】なし
