A family of mineral-analogue ceramic waste forms. Different titanate phases accept different waste ions by solid solution; phase assemblage is tailored to the waste inventory.
A multiphase Synroc formulation with zirconolite, hollandite, perovskite and titanium-oxide phases. The mineral hosts distribute different radionuclides rather than requiring one lattice to accept the entire inventory.

Synroc, or Synthetic Rock, is a type of ceramic material developed for the immobilization of radioactive waste, particularly high-level nuclear waste. It was invented in the 1970s by a team of researchers in Australia led by Professor Ted Ringwood. The primary purpose of Synroc is to encapsulate and stabilize radioactive isotopes, allowing for safer and more efficient storage and disposal.
