In this paper, the calculated compositions for three categories of SYNROC powders are recorded and the process by which the powder mixtures are prepared prior to the final hot-pressing step for densification and mineralization is described. The three categories of SYNROC compositions described are: (I) Single phase, which includes the minerals hollandite (SO3) and nepheline (SO8)) (used for cesium leach-rate comparisons in support of our SYNROC D program); (II) SYNROC C three-phase minerals (SO4, SO5, and SO8), which include hollandite, zirconalite, and perovskite; and (III) SYNROC C two-phase minerals (SO9), which include only hollandite and zirconalite. The formulated compositions for all powder mixtures covered in this report are listed.
