NOVEL THORIUM PHOSPHATES, METHOD FOR PREPARING SAME, AND USE THEREOF FOR STORING RADIOACTIVE MATERIALS |
| 摘要 |
Novel thorium phosphates, a method for preparing same, and the use thereof for storing radioactive materials, are disclosed. Said novel thorium phosphates are of formulae Th4P6O23 (I) or Th4-x M4x/v P6O23 (III), wherein M is a monovalent, divalent, trivalent or tetravalent cation, v is the state of valency of the cation and is 1, 2, 3 or 4, and x is such that 0 < x </= 3 when v = 4, 0 < x </= 0.26 when v = 3, 0 < x </= 0.1 when v = 2, and 0 < x </= 0.036 when v = 1. In particular, said cation M may be a radioactive element. |
