摘要：

Molybdenum-, copper-, and cesium-containing glass based on aluminophosphate designed to immobilize high-active wastes (HAWs), which are formed at the reprocessing of spent nuclear fuel (SNF) from Atom Peaceful Big (AMB) nuclear reactor, have been synthesized and studied by means of the X-ray diffraction and electron-microscopy methods. After quenching the melts, glass, which partially crystallizes at annealing, is formed. The introduction of magnesium oxide in aluminophosphate glass increases its crystallization resistance; and molybdenum oxide, decreases. The samples crystallize after heat treatment with the formation of aluminum and sodium-aluminum orthophosphates and solid solution of the (Na,Cs)(3-3x) Al (x) PO4 composition.
