The lattice parameters of apatite-type Ca2Ca8(SiO4)6O2 determined from X-ray powder diffraction data are inconsistent with those found in the literature for the same type of material. Hence the structure was redetermined and compared with previously

The high chemical durability of iodine-bearing apatite phases makes them potentially attractive for immobilizing radioactive iodine. Reactive spark plasma sintering provides a dense ceramic as a wasteform. A design-of-experiments (DOE) approach was a
