摘要: The last note(1) revealed the hydrothermal hot-pressing technique was capable for immobilization of radioactive wastes. By this technique, simulated high-level waste reacted with silica mixture silicastone and siliceous sinter, simultaneously formed a hardened body by under alkaline conditions. It is difficult to understand clearly reaction matrix, because has many components. one meaningful methods understanding it clarify stable products each element in matrix confirmed that Sr, most dangerous elements waste, conditions produce strontium silicate (SrSiO3)(1).
