Zirconolite Binder
Zirconolite Binder is a gel-type suspension/composition Calcia-Zirconia-Titania (CaZrTi2O7) whereby oxide powders or solutions of lanthanide/actinide compounds can be easily investigated by merely mixing them into the binder – forming coatings or “Syn-Roc” like phases. The latter have been found to immobilize/stabilize radioactive wasteforms1,2. Dried, pressed pellets can densify at <=1300 C.
