Abstract

Iodoapatite powder prepared by high-energy ball milling is densified by Spark Plasma Sintering to ∼96% theoretical density. X-ray Diffraction and First-principle Calculation indicates the sintered phase is iodine-deficient apatite with chemical composition of Pb_9.85(VO₄) ₆I_1.7 and iodine confinement over 8 wt%. Thermogravimetric analysis shows the bulk iodoapatite displays exceptionally stability without iodine release until 670°C. The greatly improved iodine confinement can be attributed to the dense matrix upon rapid consolidation from highly activated powders by mechanical attrition.
