High energy ball milled iodoapatite in the form of an amorphous matrix embedded with nanocrystals can be readily crystallized by subsequent low temperature thermal annealing, which greatly improves the thermal stability and iodine confinement.

BaTi4O9 and PbxBa1−x Ti4O9, where x is 0.1, 0.2, 0.3, 0.4, or 0.5, have been prepared by a combustion synthesis process. The process starts with spray drying aqueous solutions of Pb(NO3)2, Ba(NO3)2, TiO(NO3)2, and β-alanine with appropriate ratios. Combustion reactions occur when heating the spray-dried products to 300 °C, which convert them to BaTi4O9 and PbxBa1−xTi4O9 directly. PbxBa1−xTi4O9 (x ≧ 0.1) are low temperature, metastable phases and have not been reported before. Pb0.5Ba0.5Ti4O9 is unstable above 800 °C and cannot be sintered. All PbxBa1−xTi4O9 compositions will decompose by 1300 °C, the temperature for solid state synthesis of BaTi4O9. Single-phase PbxBa1−xTi4O9 (x = 0.1, 0.2, 0.3, 0.4), however, have been sintered at relatively lower temperatures.
