Abstract

Zircon, ZrSiO₄, is a prospective durable host material for the immobilization of excess weapons plutonium. Using cerium as a chemical analogue for plutonium, the experiments on the synthesis of Ce-doped zircon were conducted by sintering of sol-gel precursors in air and vacuum. The results showed that cerium substantially promotes zircon formation from sol-gel precursors and sintering in air is preferable for cerium incorporation in zircon structure. Based on measured lattice constants, solid solution compositions (Zr_0.96Ce_0.04)SiO₄ and (Zr_0.98Ce_0.02)SiO₄ were formed in samples sintered in air at 1400 °C and 1600 °C, respectively. The solubility limits of cerium and actinides in zircon and mechanism of zircon formation are discussed.
